Thank you, Dim!
I ran a regression test and pushed this to trunk adding a ChangeLog entry
and adjusting the commit message a bit as follows. I plan to push back to
the gcc-14 branch shortly and the gcc-13 and gcc-12 branches gradually.

libgcc: On FreeBSD use GCC's crt objects for static linking
Add crtbeginT.o to extra_parts on FreeBSD. This ensures we use GCC's
crt objects for static linking. Otherwise it could mix crtbeginT.o
from the base system with libgcc's crtend.o, possibly leading to
segfaults.
