The siglist.c is built with -fno-toplevel-reorder to avoid compiler to reorder the compat assembly directives due an assembler issue [1] (fixed on 2.39). This patch removes the compiler flags by split the compat symbol generation in two phases. First the __sys_siglist and __sys_sigabbrev without any compat symbol directive is preprocessed to generate an assembly source code. This generate assembly is then used as input on a platform agnostic siglist.S which then creates the compat definitions. This prevents compiler to move any compat directive prior the _sys_errlist definition itself. Checked on a make check run-built-tests=no on all affected ABIs.
