If the xgcc executable has not been built (or has been removed by 'make
clean') then the command to print the multilib dir fails, and so the
MULTIOSDIR variable is empty. That then causes:
/bin/sh: line 0: test: !=: unary operator expected
We can avoid it by quoting the variable.
libgcc/ChangeLog:
* Makefile.in: Quote variable.
MULTIDIR := $(shell $(CC) $(CFLAGS) -print-multi-directory)
MULTIOSDIR := $(shell $(CC) $(CFLAGS) -print-multi-os-directory)
-MULTIOSSUBDIR := $(shell if test $(MULTIOSDIR) != .; then echo /$(MULTIOSDIR); fi)
+MULTIOSSUBDIR := $(shell if test "$(MULTIOSDIR)" != .; then echo /$(MULTIOSDIR); fi)
inst_libdir = $(libsubdir)$(MULTISUBDIR)
inst_slibdir = $(slibdir)$(MULTIOSSUBDIR)
