Thomas De Schampheleire 3880a6ab3c infra: remove redundant $(call) on pkgdir, pkgname, pkgparentdir
When calling make 'functions', the $(call) keyword is only needed if the
function takes arguments. For pkgdir, pkgname and pkgparentdir this is not
the case, so we can remove the call to make things more readable.

# hyphens to underscores
# Heavily inspired by the up macro from gmsl (http://gmsl.sf.net)
# This is approx 5 times faster than forking a shell and tr, and
# as this macro is used a lot it matters
# This works by creating translation character pairs (E.G. a:A b:B)
# and then looping though all of them running $(subst from,to,text)
