Suggest or install pkg-config

[Bodigrim]

Haskell package ecosystem works better and is more secure when pkg-config executable is available. Could ghcup

• suggest to install pkg-config alongside other system packages on Unix,
• install pkg-config in MSYS environment on Windows?

Or am I barking mad?

We could. It's here https://github.com/haskell/ghcup-metadata/blob/1d55bd79dc338dfd3843d26b27dc9340b4b7f6c5/ghcup-0.0.8.yaml#L6

install pkg-config in MSYS environment on Windows?

I think we already do?

ghcup-hs/scripts/bootstrap/bootstrap-haskell.ps1

Line 536 in eebbc99

Exec "$Bash" '-lc' ('pacman --noconfirm -S --needed curl autoconf {0}' -f $PkgConf)

Nice! Is Stack able to use this MSYS environment or does it insist on installing its own?

Through a combination of these config options:

• skip-msys
• extra-path
• extra-include-dirs
• extra-lib-dirs

It's a bit manual.
