Add support for OpenRISC. See here for more details about
OpenRISC http://openrisc.io.
All buildroot included upstream binutils versions are supported.
Gcc support is not upstream, to be able to enable musl C library
support later, we use the branch with musl support.
At the moment it is possible to build a musl based toolchain,
but bootup in Qemu fails.
Gdb is only working to debug bare-metal code, there is no support
for gdbserver/gdb on Linux, yet.

unlikely to be any aarch64 based legacy projects unwilling to use a newer

gcc 4.7 introduced the sync_8 builtin functions for ARM. For ARM < v7,
this requires calling into the kernel. However, the failure path of
that call reports an error with the __write() function, which is a
glibc internal function. Therefore, it fails to link with uClibc or
musl. This was fixed in gcc 5.2.0, by replacing the __write() with
a plain write().
For sync_8 itself we have solved this with the conditions on
BR2_TOOLCHAIN_ARM_HAS_SYNC_8. However, the same function is also used
for the implementation of atomics.
For the internal toolchain, we can fix this by backporting the patch
to 4.9.4 and 4.8.5.

The current BR2_GCC_ENABLE_TLS can cause users to make incorrect
choices, and is not very useful. This options allows to decide whether
we pass --enable-tls or --disable-tls to gcc, to enable or disable
support for Thread Local Storage.
Its behavior is:
- The option is default to "y" but only exists if we're using
uClibc/NPTL or glibc.
- When we're using uClibc, the option can be disabled.
So, in practice, this means that currently:
- TLS support is always on for glibc
- TLS support is on by default for uClibc/NPTL, but can be disabled in
the configuration. This is in fact bad and causes the build failure
reported in bug #7424 (this bug is still reproducible on master)
- TLS support is always disabled for uClibc/no-thread and
uClibc/linuxthreads.
- TLS support is always disabled for musl. This does not cause any
build failure, but musl can use TLS support, and therefore be more
efficient. According to
http://www.openwall.com/lists/musl/2012/10/04/1, "Note that if you've
been building gcc with --disable-tls, __thread was already working
but gets emulated (very poorly; it's slow and will abort() if it runs
out of memory) through libgcc.".
So, this commit completely removes the BR2_GCC_ENABLE_TLS and instead
makes the right choice inside gcc.mk directly:
- TLS support enabled for glibc, musl and uClibc/NPTL
- TLS support in other cases, i.e uClibc/no-thread and
uClibc/linuxthreads.
We have intentionally *not* added the option to
Config.in.legacy. Indeed, the new behavior is *exactly* the same as the
older behavior, with the exception of:
- People can no longer disable TLS support in uClibc/NPTL, which was
anyway causing a build failure and therefore was not used.
- TLS support is now enabled on musl, but people using musl already had
BR2_GCC_ENABLE_TLS not set, so they wouldn't get the legacy warning.
Fixes bug #7424.
