'pkg-config-for-target' just returns "pkg-config" when compiling
natively, so the 'if' can be dropped here and the "-
DPKG_CONFIG_EXECUTABLE=..." be made unconditional.

For clarity, I would put the 'list' on a separate line, though for
style reasons that might require removing the quasiquote and turning it
in a 'list': (arguments (list #:phases #~(foo ...) #:configure-flags
#~(bar ... #$(pkg-config-for-target)))).

Greetings,
Maxime.
