FreeBSD: Stop linking _p libs for -pg as of FreeBSD 14
As of FreeBSD version 14, FreeBSD no longer provides profiled system
libraries like libc_p and libpthread_p. Stop linking against them if
the FreeBSD major version is 14 or more.
gcc:
* config/freebsd-spec.h: Change fbsd-lib-spec for FreeBSD > 13,
do not link against profiled system libraries if -pg is invoked.
Add a define to note about this change.
* config/aarch64/aarch64-freebsd.h: Use the note to inform if
-pg is invoked on FreeBSD > 13.
* config/arm/freebsd.h: Likewise.
* config/i386/freebsd.h: Likewise.
* config/i386/freebsd64.h: Likewise.
* config/riscv/freebsd.h: Likewise.
* config/rs6000/freebsd64.h: Likewise.
* config/rs6000/sysv4.h: Likeise.
(cherry picked from commit 48abb540701447b0cd9df7542720ab65a34fc1b1)
