Starting with fpc-2.6.2 release, 
this completes successfully for me:
make distclean crossinstall OS_TARGET=win64 CPU_TARGET=x86_64 PREFIX=e:/pas/fpc-2.7.1

Stating with a 2.7.1 win32 binary:
E:\pas>fpc -iVDW
2.7.1 2013/03/28 2.7.1-r1:24029M
(Meaning that I do have some local modifications, but I doubt those interfere with your problem...)
I get the same success...

Did you use a distclean before the crossinstall?
win32 fpmake.exe generated for native win32 target might be a problem...
I checked, and indeed, if you just do a native install
followed by a crossinstall without a distclean in between, 
you do get

So the solution to your problem really is
to run a 'distclean' make target before the 'crossinstall' target.
