stdio: Remove the usage of $(fno-unit-at-a-time) for errlist.c The errlist.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_errlist_internal internal 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 errlist-data.S which then creates the compat definitions. This prevents compiler to move any compat directive prior the _sys_errlist_internal definition itself. Checked on a make check run-built-tests=no on all affected ABIs.
