libgcc: Support -mcall-ms2sysv-xlogues on FreeBSD/x86

With the bulk of the gcc.target/x86_64/abi tests fixed on FreeBSD/amd64,
a couple remain:

FAIL: gcc.target/x86_64/abi/ms-sysv/ms-sysv.c -mcall-ms2sysv-xlogues -O2 "-DGEN_ARGS=-p0\ --omit-rbp-clobbers" (test for excess errors)

and five more.  They all fail to link like

gld-2.46: /tmp//ccXprYoX.o: in function `msabi_00_0':
ms-sysv.c:(.text+0x30): undefined reference to `__sse_savms64f_12'

and many more missing symbols.  Those are usually provided in libgcc.a
by i386/t-msabi, so this patch includes them on FreeBSD/x86, too.  As
with the previous fixes, the resms64*.h and savms64*.h files need to
include .note.GNU-stack, too.

Bootstrapped without regressions on amd64-pc-freebsd15.0 with both gld
and /usr/bin/ld (lld), and x86_64-pc-linux-gnu.
