[pacman-dev] [PATCH] makepkg: use type -p's return value for PATH checks

[Andres P]

Determining if a command is in PATH now relies on type -p's return value
instead of a string check.

And gettext was previously being checked with type -t, which is
inconsistent with the rest of the tests pertaining commands that aren't
expected to be functions nor builtins.
