app-text/discount: respect gentoo's CC propagation

Before the change build log looks like:
   cc -I. ... -g -O2 -pipe -fdiagnostics-show-option -frecord-gcc-switches -fPIC -I. -c main.c
After the change:
   x86_64-pc-linux-gnu-gcc -I. ... -g -O2 -pipe -fdiagnostics-show-option -frecord-gcc-switches -fPIC -I. -c main.c

See https://devmanual.gentoo.org/ebuild-writing/functions/src_compile/building/
for more details.
