Reproducible: Always Steps to Reproduce: 1. crossdev -t x86_64-gentoo-linux-musl --stable Actual Results: checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. make[1]: *** [Makefile:11760: configure-target-libquadmath] Error 1 Please read the following links: https://gcc.gnu.org/legacy-ml/gcc/2010-12/msg00438.html https://gcc.gnu.org/legacy-ml/gcc-patches/2010-12/msg01447.html It looks like this issue is related to configure.ac. https://gcc.gnu.org/git/?p=gcc.git;a=history;f=libquadmath;hb=HEAD Libquadmath project looks like abandoned, it received less than 100 commits for the last 10 years. I want to recommend disabling it by default.

When initial toolchain is bootstrapped libc is not available yet. The change disables libquadmath for bootstrap cases when libc is not installed yet. gcc-stage2 still uses platform defaults for libquadmath.
