[fpc-devel] Cross compiling x86_64 -> ARM (RPi) | EABI mis-match.

[Bruce Tulloch]

Okay, thanks, so I should be able to simply patch the makefile in my copy
of the fpc source to apply the correct assembler parameters when
(re)building the RTL to fix this problem, right? If so, I'll look into
doing this when I've resolved the cthreads issue. -b
