There are some bugs in Apple's new linker that probably will not
be fixed when Xcode 15 is released (some time soon). We fix/work
around them but it is too much to backport them all. Force old
Apple linker to work around.

Updates #61229.
For #62597.

…d mode on darwin

[This is a (manual) backport of CL 527415 to Go 1.20.]

Currently, linking a Go c-shared object with C code using Apple's
new linker, it fails with

% cc a.c go.so
ld: segment '__DWARF' filesize exceeds vmsize in 'go.so'

Apple's new linker has more checks for unmapped segments. It is
very hard to make it accept a Mach-O shared object with an
additional DWARF segment.

We may want to stop combinding DWARF into the shared object (see
also #62577). For now, disable DWARF by default in c-shared mode
on darwin.

Updates #61229.
For #62597.

…warning for ld-prime

ld-prime emits a deprecation warning for -bind_at_load. The flag
is needed for plugins to not deadlock (#38824) when linking with
older darwin linker. It is supposedly not needed with newer linker
when chained fixups are used. For now, we always pass it, and
suppress the warning.

Updates #61229.
For #62597.
