[fpc-devel] MacOS Mojave beta - crt1.o not installed to /usr/lib

[Michael Ring]

This small patch helped me to get rid of the need to define 
-XR/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/ in /etc/fpc.cfg


It would be greet to have something similar in the upcoming 3.0.5 
release (and of course in trunk) so that also building lazarus with a 
3.0.5 compiler works (It currently fails without the entry in fpc.cfg)
