continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
Naive concatenation of $LD_LIBRARY_PATH can result in an empty
colon-delimited segment; this tells glibc to load libraries from the
current directory, which is definitely wrong, and may be a security
vulnerability if the current directory is untrusted. (See #67234, for
example.) Fix this throughout the tree.

"platforms.gnu" has been linux-only since at least 17.03:
$ nix eval -f channel:nixos-17.03 lib.platforms.gnu
[ "i686-linux" "x86_64-linux" "armv5tel-linux" "armv6l-linux" "armv7l-linux" "aarch64-linux" "mips64el-linux" ]
Unlike platforms.linux, platforms.gnu indicates "must use glibc"
which for the most part is not intended.
Replacing platforms.gnu with platforms.linux would be the same "today"
but let's err on preserving existing behavior and be optimistic
about platforms these packages work on.
Error is:
ERROR: In procedure %resolve-variable:
ERROR: Unbound variable: use-syntax
FAIL: sxml.ssax.scm
Also add pkg-config so that configure script can find libguile.
Relevant to #28643
Some of these should be longDescriptions, but most others just
shouldn't contain newlines. E.g. write
description = "Bla";
and not
description = ''
Bla
'';
This pollutes "nix-env -qa --description" output.
