Hello!

The attached patch contains a change suggested by Károly Balogh from
upstream to work around the current FPU issue on m68k [1].

With the patch applied, I was able to bootstrap fpc for m68k natively
and uploaded the resulting binaries.

Thus, please drop the current m68k patch [2] and replace it with the
attached one to fix the FTBFS until the upstream bug [1] has been
fixed.

Thanks,
Adrian

Description: Disable FPU inlining on m68k
 There is a bug in the FPU code on m68k which causes the
 bootstrap to fail (upstream bug #37250). Until the bug
 has been fixed, disable FPU inlining to work around the
 issue and fix the bootstrap on m68k.
