build: Set MULTIOSDIR to ".".

This was causing errors due to an unquoted argument to the test utility:

    Checking multilib configuration for libgcc...

The "unary operator expected" error seems to be caused by this line
(libgcc/Makefile.in:291):

    MULTIOSSUBDIR := $(shell if test $(MULTIOSDIR) != .; then echo /$(MULTIOSDIR); fi)
