[PATCH] Make libgcc.a symbols .hidden (fix for non-GNU make, take 2)

[John David Anglin]

> Please remove @ in:
> echo '	@$(NM_FOR_TARGET) '${SHLIB_NM_FLAGS} ${o}' | $(AWK) '\''NF == 3 { print ".hidden", $$3 }'\'' | $(GCC_FOR_TARGET) $(LIBGCC2_CFLAGS) -r -nostdinc -nostdlib -o $@ '${o}' -xassembler -'
> See what exactly it prints. Also sticking "tee /tmp/hidden.s | " right
> before $(GCC_FOR_TARGET) might give some interesting info too
> (as well as plain nm -pg libgcc/_divI.o).

/tmp/hidden.s:
.hidden $$divI
.hidden $$divoI

On the PA, there needs to be whitespace (e.g., a tab) before the
".hidden" directive.
