[fpc-pascal] MacOSX Mojave

[C Western]

Possibly unwisely, I updated by Mac to Mojave. I found that things 
(including 32 bit apps) worked, but:

I had to add

-Fl/Applications/Xcode.app/Con
tents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib

to my fpc.cfg to avoid "/usr/lib/crt1.o not found" errors. It seems as 
though the startup files are no longer in /usr/lib

The gdb from MacPorts also didn't seem to work. I had some success using 
lldb - I notice an alpha package for this can be installed in lazarus, 
and this seemed to work, at least on the basic test I did.
