compel: fix build break on ppc64le

This patch fix a build break on ppc64le introduced by changes in the
compel's build option.

I factorized the common CFLAGS to make easier identifying particular
flags required by some architectures.

Fixes: fef01d79f7ee ("compel: cli -- Add more flags into cflags report")
travis-ci: success for compel: fix build break on ppc64le
