A toolchain uclibc-ng-1.0.43, binutils-2.40 and gcc-13.2.0 hits the
following error when building:
ld.bfd: isl_test2.o: non-canonical reference to canonical protected function `__pthread_key_create' in x86_64-multilib-linux-uclibc/sysroot/lib64/libc.so.1
ld.bfd: failed to set dynamic section sizes: bad value
The reference comes from libgcc where it is using the
__pthread_key_create() symbol to detect the use of pthreads with GNU
libc. Prevent this on uclibc-ng with an explicit condition.
