Log Message:
gcc/vax: XXX: Forcibly disable gas(1) directives for CFI table
Otherwise, wired relocation occur for readonly section `.eh_frame',
by which libc.so cannot link:
----
warning: dynamic relocation to `?' in readonly section `.eh_frame'
warning: creating DT_TEXTREL in a shared object
.eh_frame_hdr refers to overlapping FDEs
final link failed: bad value
----
This workaround has been introduced by vax.c, v1.15:
http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gcc/dist/gcc/config/vax/Attic/vax.c#rev1.15
but accidentally lost during GCC 12.3.0 merge.
