eglibc: enable support in the Buildroot toolchain backend Using the newly introduced 'eglibc' package, this commit enables the option of building a toolchain using the eglibc C library in the Buildroot toolchain backend. In details, this commit: * Creates a choice to select uClibc or eglibc in the Buildroot toolchain backend (in toolchain/toolchain-buildroot/Config.in), and removes the fact that the Buildroot toolchain backend forcefully enables uClibc (toolchain/Config.in). * Creates a BUILDROOT_LIBC variables, which points to the package implementing the C library (i.e either 'uclibc' or 'eglibc'). * Modifies the gcc-final and gcc-intermediate makefiles to use the BUILDROOT_LIBC variable instead of hardcoding the use of uclibc. * Ensures that TLS support is always enabled when building eglibc.

toolchain: include C libraries in legal-info So far, the legal-info infrastructure was not exporting the legal info for the C libraries. This is because the legal-info only acts on packages defined in $(TARGETS). But the C libraries are never added to $(TARGETS), since there is no corresponding BR2_PACKAGE_<C-LIBRARY>. This patch adds such symbols for the 4 C libraries we support in our internal backend: uClibc, glibc, eglibc and musl. Signed-off-by: "Yann E.

uclibc: adapt thread implementation selection to uClibc-ng uClibc-ng does not support linuxthreads or linuxthreads.old on architectures that have NPTL support. This creates another complicated dependency: dependeing on the uClibc version being used, not the same thread implementations are available. In order to handle this situation, this patch introduces three hidden booleans: - BR2_UCLIBC_VERSION_SUPPORTS_LINUXTHREADS - BR2_UCLIBC_VERSION_SUPPORTS_LINUXTHREADS_OLD - BR2_UCLIBC_VERSION_SUPPORTS_NPTL They are selected by the different uClibc versions, depending on which thread implementation they support on the different architectures. Then, the choice of the thread implementation can rely on those booleans to know if a given thread implementation is available in the current architecture / uClibc version selection. This makes sure that unusable thread implementation do not get selected, therefore fixing build issues such as: http://autobuild.buildroot.org/results/89e/89e423bee040cbce3e82cd89f1191efaac490c0d/ The support table is as follows (only taking into account architectures that allow the selection of BR2_TOOLCHAIN_BUILDROOT_UCLIBC, other architectures are not considered) : ----uclibc---- uclibc-xtensa- --uclibc-arc-- --uclibc-ng--- LT LT.old NPTL LT LT.old NPTL LT LT.old NPTL LT LT.old NPTL arc(le|eb) y y n n n n (1) arm(eb) y y y n y y (2) bfin n y n y y n i386 y y y n n y (3) m68k y y y y y n mips(64)(el) y y y n n y powerpc y y y n n y sh y y y n n y sparc y y y n n y xtensa n y n n n y x86_64 y y y n n y (1) : uclibc-ng only has NPTL support for ARC but it requires a more recent compiler version that hasn't been officially released by Synopsys.

uclibc: remove version from the uclibc-ng config option For the moment, we probably don't want to have several versions of uClibc-ng supported at the same time. In preparation to the bump of uClibc-ng to 1.0.1, this commit gets rid of the version number from the uclibc-ng config option so that we don't have to rename this option over and over again each time a new uClibc-ng release is made. This would be annoying in terms of Config.in.legacy handling. Since the option BR2_UCLIBC_NG_VERSION_1_0_0 has never been part of any Buildroot release, we don't have to add anything to Config.in.legacy.

uclibc: add ability to use uClibc-ng 1.0.0 This commit adds support for a new uClibc version: uClibc-ng 1.0.0. Since its build system is for now exactly the same as the one of uClibc, we don't create a new package, but instead simply add it as a new uClibc version. The only special trick needed is the creation of a symlink to the program interpreter, due to a mismatch between the program interpreter file name generated by uClibc-ng and the one used by gcc. This patch is heavily based on previous work from Waldemar Brodkorb. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

uclibc: add a special Xtensa version Currently, the Xtensa architecture uses the "snapshot" version of uClibc. This means that the build is not reproducible, since it will pick whatever latest version of uClibc is available at the moment of the build. This commit replaces that by adding a special Xtensa version, which points to a well-known Git commit. This is something we should hopefully be able to remove once the uClibc people realize that doing a 0.9.34 release would be useful.

uclibc: remove version from the uclibc-ng config option For the moment, we probably don't want to have several versions of uClibc-ng supported at the same time. In preparation to the bump of uClibc-ng to 1.0.1, this commit gets rid of the version number from the uclibc-ng config option so that we don't have to rename this option over and over again each time a new uClibc-ng release is made. This would be annoying in terms of Config.in.legacy handling. Since the option BR2_UCLIBC_NG_VERSION_1_0_0 has never been part of any Buildroot release, we don't have to add anything to Config.in.legacy.

uclibc: add a special Xtensa version Currently, the Xtensa architecture uses the "snapshot" version of uClibc. This means that the build is not reproducible, since it will pick whatever latest version of uClibc is available at the moment of the build. This commit replaces that by adding a special Xtensa version, which points to a well-known Git commit. This is something we should hopefully be able to remove once the uClibc people realize that doing a 0.9.34 release would be useful. Should probably fix: http://autobuild.buildroot.org/results/5d6/5d6072a038acf894d832704e36c1d43f0254abf5/build-end.log at least I wasn't able to reproduce the build problem.

uclibc: add explicit setup of ARC-specific options As with other architectures for ARC we need to have an ability to set specific options in uClibc. In particular this is required for selection of ARC ISA version.

eglibc: enable support in the Buildroot toolchain backend Using the newly introduced 'eglibc' package, this commit enables the option of building a toolchain using the eglibc C library in the Buildroot toolchain backend. In details, this commit: * Creates a choice to select uClibc or eglibc in the Buildroot toolchain backend (in toolchain/toolchain-buildroot/Config.in), and removes the fact that the Buildroot toolchain backend forcefully enables uClibc (toolchain/Config.in). * Creates a BUILDROOT_LIBC variables, which points to the package implementing the C library (i.e either 'uclibc' or 'eglibc'). * Modifies the gcc-final and gcc-intermediate makefiles to use the BUILDROOT_LIBC variable instead of hardcoding the use of uclibc. * Ensures that TLS support is always enabled when building eglibc.
