Actually, an idea.

fppkg (the standalone) has a -C option, and one could have fpcmkcfg -3 and -4 to
create a correct config for a compiler that is not on the PATH and place it next
to fpc.cfg.

If the Lazarus packager fppkghelper would offer the same and try loading
'$(Path($(CompPath(IDE)))\fppkg.cfg', I think most problems would be solved.
CompPath(IDE) isn't entirely correct either, but it would be less wrong than the
current order...
