Bug#980841: fpc: Please add workaround patch to fix FTBFS on m68k

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.
