Tested with .../configure --target=c6x-uclinux [...] && make all-gcc, ok for trunk?
-- >8 -- Currently, cross-compiling with --target=c6x-uclinux (and several other) fails due to: ../../src/gcc/config/linux.h:221:45: error: 'linux_fortify_source_default_level' was not declared in this scope #define TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL linux_fortify_source_default_level In the PR Andrew mentions that another fix would be in config.gcc, but really, here I meant to use the target hook for glibc only, not uclibc. This trivial patch fixes the build problem. It means that -fhardened with uclibc will use -D_FORTIFY_SOURCE=2 and not =3.
