Thomas Petazzoni 371327f7b6 Revert "packages infra: add function to get a Kconfig option"
This reverts commit c28a28eed1. The
whole host-lzop optional dependency logic cannot work, since the
configuration file will only be known after the kernel sources are
extracted, if an internal kernel defconfig is used, which is quite
common.

# UPPERCASE Macro -- transform its argument to uppercase and replace dots and
# 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)
