Btw. do you have a bugzilla account? I bet instead of opts->x_linux_libc != LIBC_GLIBC it needs to use #ifdef OPTION_GLIBC if (!OPTION_GLIBC) #endif or so. I think the first committed patch actually used that but used it in #if directive, which is wrong because it is something that needs to be evaluated at runtime. That doesn't work well either, because the *supports_split_stack hooks have opts argument and OPTION_GLIBC doesn't take that. So, here is a patch that introduces OPTION_*_P macros that take opts as an argument and redefines OPTION_* using those (similarly to how the option scripts create TARGET_*_P and TARGET_* macros). 2022-01-24 Jakub Jelinek <jakub@redhat.com> PR bootstrap/104170 * config/linux.h (OPTION_GLIBC_P, OPTION_UCLIBC_P, OPTION_BIONIC_P, OPTION_MUSL_P): Define.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
