Indeed - the IDE doesn't need to call ppcx86 directly, but it can simply
pass ~/fpc/2.7.1/lib/2.7.1/ to fpc via -Xp and let it do its job (it
should also call fpc from ~/fpc/2.7.1/lib/2.7.1/ in such a case to cater
for situations like support of a new platform support not available with
the latest released version).
