While this has been Ovfork.S forever on i386 it differs from other
syscalls that require wrappers for no obvious reason so fix that.

libc: Centralize non-building of sbrk stubs2024-01-02T16:22:13ZBrooks Davisbrooks@FreeBSD.org2024-01-02T16:22:13Zurn:sha1:94671881419f0fb8014006266e5505feaf23daeb
The actual implementation of sbrk(2) is on top of the undocumented
break(2) system call. On powerpc* this means we don't build _sbrk and
__sys_sbrk which were neither used nor exposed for linkage. Otherwise
it is a no-op.
The addition to lib/libc/sys/Makefile.inc is a direct commit to
stable/14 in lieu of merging the removal of the sbrk and sstk syscalls.

libc: centralize a few numeric symbols2023-12-13T22:08:14ZBrooks Davisbrooks@FreeBSD.org2023-11-15T23:42:37Zurn:sha1:f695db9fbae9786aac0e8b925bef6b78f745c13a
fabs, __infinity, and __nan are universally implemented so declare them
in gen/Symbol.map.
We would also include __flt_rounds, but it's under FBSD_1.3 on arm so
until that's gone we're stuck with it. Likewise, everyone but i386
implements fp[gs]etmask.

These symbols are universally exposed and documented so declare them
centrally. Double- and triple-underscore versions exist on some
platforms, but leave those alone for now.

These sys/cdefs.h are not needed. Purge them. They are mostly left-over
from the $FreeBSD$ removal. A few in libc are still required for macros
that cdefs.h defines. Keep those.
