When cross-build support was added for mkig{name,list} was added, the
CFLAGS and CPPFLAGS should have been updated to the HOSTCFLAGS/HOSTCPPFLAGS
vars.
In a cross-build scenario, some of these flags don't match what the
compiler can understand (because they may be architecture specific) and
may fail the build.
Using the HOSTCFLAGS/HOSTCPPFLAGS works and builds successfully.
Also the output binary works on the target.
