We need netbsdCross.ld_elf_so to be the dynamic linker in cross
netbsd's bintools, but netbsdCross doesn't have a libc in stdenv. So
instead, use netbsdCross.libc for netbsdCross.ld_elf_so.
Notes:
- compat: Needs a header from common merged with it's wrapper.
- librt: Needs the jemalloc sources.
- libc: install libc_pic.a
This was the behaviour on NetBSD 8.0, and ld.elf_so (in its current
configuration) requires it. We could also have disabled PIC in
ld.elf_so.
- sys: fix build
We use a more recent version of binutils than NetBSD 9.1 does, so we
need to backport a patch from CURRENT.

"common" is just a lot of shared code, not a component in and of
itself. There's no Makefile, so if we try to build it Make will go up
a directory and try to build all of NetBSD.
This is another one of those packages that's just a rebuild of a
certain part of libc...
Tested by building pkgsCross.x86_64-netbsd.netbsd.librt on
x86_64-linux.
libc's postPatch was entirely fixes for librt, so move that to librt
and inherit it in libc.
82c231d17e ("netbsd: Generalize builder to any-bsd setup hook")
missed libterminfo when it added bsdSetupHook to every other
package. (I checked it didn't miss anything else.)
It also didn't change a NETBSDSRCDIR to BSDSRCDIR, but in fairness
that line was added about half an hour before the setupHook change was
merged in a16384e118.
Fixes: 82c231d17e ("netbsd: Generalize builder to any-bsd setup hook")
Tested building pkgsCross.x86_64-netbsd.netbsd.libm from x86_64-linux.
At some point we should probably set SHLIBINSTALLDIR in the setupHook,
but I think I'd like to get everything working first, and then make
changes that affect all the builds like that. It's easier to spot
regressions when you know _everything_ worked before.
- No splicing makes everything less finnicky.
- Normal bootstrapping matches e.g. linux where kernel headers are also
`stdenvNoCC` but part of this stage.
Before, we were only building the headers, firmware, and bootloader.
CONFIG could be overridden to use another pre-defined kernel, but
there's no way to pass a custom kernel configuration yet.
Tested booting the built kernel in a NetBSD VM.
For some reason fetchcvs was taken from the cross package set when
cross compiling netbsd.* instead of from buildPackages. I suspect that
this was no issue previously because it just could be substituted as it
only ever produced fixed output derivations. However since
00a2084a40 the evaluation of fetchcvs
would depend on `stdenv.cc` (via its openssh dependency). Since
netbsd.libc is required to evaluate stdenv.cc this caused a infinite
recursion when staging the cross stdenv for pkgsCross.amd64-netbsd. The
fix for this is pretty easy: Just take fetchcvs from buildPackages
explicitly instead of hoping for mkDerivation to get it right.
Resolves #119323.
