It surprises me this works with FPC 3.0, as cross-compilation-specific 
options should be passed via CROSSOPT instead of OPT.

Anyway, the non-hacky way to specify a cross-compilation sysroot is with 
-XR instead of -Xd -Fl.

So try this instead:

make distclean crossall crossinstall OPT="-O2 -XX -CX -Xs" 
CROSSOPT="-XR/home/epidata/Apple/SDKs/MacOSX10.5.sdk -Aas-darwin" 
CPU_TARGET=i386 OS_TARGET=darwin BINUTILSPREFIX=i686-apple-darwin10- 
INSTALL_PREFIX=~/fpc

If you split the make invocations into one per command, you can also add 
-j 4 FPMAKEOPT="-T 4" for "crossall" to significantly speed up the process.
