libiconv is already defined per-platform. The actual libiconv library
won't be built on platforms like Linux where it doesn't need to be, so
there's no need to maintain a separate platform list here.
Required to build for FreeBSD.
As the comment says, this should only have happened on Linux, not all
non-Darwin platforms.
Fixes pkgsCross.x86_64-netbsd.fzf.
Fixes: 1693ed2be9 ("fzf: wrap 'perl' in scripts with LOCALE_ARCHIVE")
systemd does not support being built statically[1], which means that,
prior to this patch, nothing that depends on udev can be built
statically. libudev-zero is a daemonless implementation of libudev,
that supports being built statically. So, by setting udev to be
libudev-zero when systemd is unavailable, we can get static builds of
packages like linuxPackages.usbip.

"llvm-as is an LLVM IR -> LLVM bitcode assembler not a system
assembler"[1], and therefore should not be linked as "as".
The "as" symlink was removed in 46e5ea5af6 ("llvm*: remove symlinks
to llvm-diff, llvm-as and associated LLVM IR utilities."), but that
was partially reverted by b331c72f03 ("llvm: setup some symlinks for
compatibility with binutils"), which restored a bunch of symlinks that
were incorrectly removed, but also incorrectly restored "as". This
was pointed out[2] at the time but apparently never fixed.

We were missing symlinks for some programs e.g. strings, which caused
e.g. pkgsLLVM.x264 to fail to build.
Here, I have filled in all the symlinks that LLVM would create if
built with the LLVM_INSTALL_BINUTILS_SYMLINKS option. Where an
existing symlink's target has changed, it's to avoid a double
indirection e.g. strip -> llvm-strip -> llvm-objcopy has because just
strip -> llvm-objcopy.
There's also the related problem that we are creating a as -> llvm-as
symlink, which doesn't make sense, but I'll remove that in a
subsequent commit so that if it somehow breaks something it's easy to
revert just that change.
