base-foc: contrib compile errors

[Martin Stein]

A similar problem occurs when building on fiasco:

The error

  Program bootstrap/bootstrap
make[6]: Nothing to be done for `all'.
  ... Generating bootstrap.ld
cc1: error: missing argument to "-P"

is caused by the '-P' in

$(LDSCRIPT): $(LDSCRIPT).in $(SRC_DIR)/Makefile $(BOOTSTRAP_LD_dep)
	@$(GEN_MESSAGE)
	$(VERBOSE)cpp -P $(CPPFLAGS) -DLINKADDR=$(DEFAULT_RELOC_$(ARCH)) $< $@;

in

base-fiasco/contrib/fiasco/snapshot/l4/pkg/bootstrap/server/src/Makefile

and can be solved by using '-P="$(CPPFLAGS)"'
then the error

/usr/local/genode-gcc/bin/genode-x86-ld:bootstrap.ld:1: ignoring invalid
character `#' in expression
/usr/local/genode-gcc/bin/genode-x86-ld:bootstrap.ld:1: syntax error

leds to <BUILD_DIR>/l4/pkg/bootstrap/server/src/OBJ-x86_586/bootstrap.ld
where removing the faulty comment style is again the problem.

After this the build and run succeeds.
The problems do not occur with other L4 based kernels.
