Remove .weak, .weakext configure tests.
There are configure tests for assembler .weak support, and, as a fallback, for .weakext support. .weakext appears to be an ECOFF thing (although a few ELF targets support it as well). .weak has been supported by the GNU assembler for ELF targets since version 2.2, so given the requirement for ELF the configure tests are obsolete; this patch removes them. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_asm_weak_directive): Remove configure test. (libc_cv_asm_weakext_directive): Likewise. * configure: Regenerated. * config.h.in (HAVE_ASM_WEAK_DIRECTIVE): Remove #undef. (HAVE_ASM_WEAKEXT_DIRECTIVE): Likewise. * include/libc-symbols.h [!HAVE_ASM_WEAK_DIRECTIVE && !HAVE_ASM_WEAKEXT_DIRECTIVE]: Remove #error. [HAVE_ASM_WEAKEXT_DIRECTIVE]: Remove conditional code. [!HAVE_ASM_WEAKEXT_DIRECTIVE]: Make code unconditional.
