ld: Compile some tests with -mdirect-extern-access
When GCC enables -mno-direct-extern-access by default, some tests fail
without -mdirect-extern-access. Define DIRECT_EXTERN_ACCESS_CFLAGS
to compile these tests with -mdirect-extern-access. Also pass
"-z noindirect-extern-access" to linker to support the C library
compiled with -mno-direct-extern-access.
