I can reproduce this, or something very similar for the clean/distclean
targets, if I have no FPC installed on my machine, but I specify PP= as a
Makefile argument to a "bootstrap" compiler binary, and I use OS_TARGET=
as well, for crosscompiling.

For example, if I try this on Linux/x86_64:
make clean OS_TARGET=aros PP=/path/to/bootstrap/ppcx86-3.2.2

I get a lot of messages like:

ake -C compiler distclean
make[1]: Entering directory '/home/charlie/Develop/fpc/source/compiler'
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
make[1]: -iTP: Command not found
/bin/rm -f ppcrossx64 ppc ppc1 ppc2 ppc3 ./msg2inc pp1.wpo pp2.wpo

So there's definitely something fishy with the bootstrap/PP compiler use,
if the build box has no FPC installed otherwise. Which to my
understanding, it shouldn't be needed, if PP is specified?

Interestingly, if I don't specify OS_TARGET, the problem doesn't occur.

Note that for a real build ("all" or "crossall" target), the specified PP
compiler still gets used as expected.
