When an external toolchain without thread debug is used, the gdb package can be selected, but no version can be choosen, since none match any of the requirements. This leads Buildroot to try to build gdb for the target without a version being defined, as in the following build log: http://autobuild.buildroot.org/results/84e8fd2df0cc22448052a572c2e9a6e03dd137eb/build-end.log To fix this, we adjust the dependencies of the BR2_PACKAGE_GDB option so that the package as a whole is not selectable when the required conditions are not met. Basically, we have the choice of: * Having a toolchain that supports thread debugging, which is needed for gdb >= 7.x * Having BR2_DEPRECATED enabled, which allows gdb 6.8 to be selected, which doesn't require thread debugging * Using bfin, since this architectures has a special old gdb version Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
