Especially as a new user it is a much better experience to receive a
proper help response to `-h`. Currently passing `-h` will cause some
runtime error with the `git remote` error help being shown. Not very
helpful.
It doesn't hurt to be a bit more user friendly in this case.
Newer versions of perf in Linux 5.1+ support disassembling and
annotating eBPF programs inside the kernel. In order to do this, it uses
libbfd's support for bpf disassembly. There are two parts: libopcodes
and libbfd.
The 'perf' build system seems to expect libopcodes/libbfd to go "hand in
hand" -- always together, if one or the other is installed. If the build
system detects libbfd is available, then an import of <dis-asm.h> is
performed, but this fails since it wasn't in the buildInput. Fixing this
should be an easy, backwards-compatible change.
Fixes#60891, allowing linuxPackages_testing.perf to build again
(currently kernel version 5.1.0-rc7).

The previous hash was generated on aarch64. Due to https://github.com/NixOS/nixpkgs/issues/60668 the hash is different on different platforms. I am updating to use the x86_64-linux hash to fix building on hydra.
the pypi package includes pre-cythonized versions of some components,
however these were cythonized with a py3.7-unaware cython which is what
caused the main breakage. fetching the equivalent version from github
allows us to offer either the pure-python version or one we cythonize
ourselves if the cython package is provided.
the added bonus of using a github checkout is that the tests are included,
so enable these.
these tests revealed that for full py3.7 compatibility an additional patch
is needed from an upstream PR.
libgcrypt-1.5's configure script incorrectly detects x86_64-apple-darwin
(macOS) as an ELF platform. This causes failures when compiling assembly
sources. Backport libgcrypt's fix for this issue, fixing libgcrypt-1.5's
build on macOS.
Remove UnicodeCollate dependency, which is part of Perl 5.28 and
does not exist separately anymore.
Add PerlIO::utf8_strict, which lack thereof Biber complains about
during build.
