Currently 'guix build' supports '--target=' option to allow cross-compilation,
but 'guix environment' doe not. Sometimes it would be nice to peek at the
environment that 'guix build' creates.
When debugging 're2' cross-compilation error I used the following command
to build a package:
./pre-inst-env guix build --check re2 --target=alpha-unknown-linux-gnu --no-grafts
I was not sure what does g++ vs. TARGET-g++ means in guix.
Would be nice to have an ability to get exactly build environment as:
./pre-inst-env guix environment re2 --target=alpha-unknown-linux-gnu --no-grafts
