linker: use wildcards in rel-sections.ld

Update rel-sections.ld to use wildcards instead of
spelling out those sections one by one.

Also, for POSIX, don't include this and turns off
the warnings. With different host toolchain across
different OS, it would be maintanence nightmare
to account for all those combinations. So this reverts
the POSIX linker script to before the first orphan
section changes.

Fixes #10493
