Jonathan Ringer 9bb3fccb5b treewide: pkgs.pkgconfig -> pkgs.pkg-config, move pkgconfig to alias.nix
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.

# Unlike libtool, vanilla Meson does not pass any information
# about the path library will be installed to to g-ir-scanner,

# library install_dir to g-ir-scanner.

# In common distributions, RPATH is only needed for internal libraries so
# meson removes everything else. With Nix, the locations of libraries
# are not as predictable, therefore we need to keep them in the RPATH.
# At the moment we are keeping the paths starting with /nix/store.

# When Meson removes build_rpath from DT_RUNPATH entry, it just writes
# the shorter NUL-terminated new rpath over the old one to reduce
# the risk of potentially breaking the ELF files.
# But this can cause much bigger problem for Nix as it can produce
# cut-in-half-by-\0 store path references.
# Lets just clear the whole rpath and hope for the best.
