I thought I had this working. Everything is compiled with -CX -XX,
but I only have .a files in my i386-linux directory, and my -va
compile logs from the other architectures all say..
unit STRUTILS can't be smart linked, switching to static

Smart linking does not happen using .a files on Darwin. Smart linking
is performed by the Darwin linker (as of the one included with Xcode
1.5 and higher) using the plain .o files. All that needs to be done is
to add ".subsections_via_symbols" at the end of an assembler file
(which FPC does when you use -CX) and pass -dead_strip to the linker
when linking (which FPC does when you use -XX).
Please file a bug to have this warning only shown for Darwin in case a
unit has been compiled without -CX.
I have no idea why it wouldn't work if you cross-compile, since as
explained it's just a matter of having a single line in the assembler
files and passing a parameter to the linker.
