Remove -static-libgcc configure test.
There is a configure test for -static-libgcc. GCC added this option in version 3.0, so this test is obsolete; this patch removes it. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_gcc_static_libgcc): Remove configure test. * configure: Regenerated. * config.make.in (static-libgcc): Remove variable. * Makerules (build-shlib-helper): Use -static-libgcc instead of $(static-libgcc). (build-module-helper): Likewise.
