fpc 1.9.1. doesn't call asw and ldw, but as and ld, unless ypu tell
differently.

With fpc 1.9.1 I use the XPi686-pc-mingw32- option. 

make OPT="-XPi686-pc-mingw32-"

make sure these binaries are in your path. If not do
make OPT="-XPi686-pc-mingw32- -FD/path/to/the/binutils"

Also be aware you only can hae one set of lcl units present at the time,
because compiling for win32 overwrites the linux lcl units.
