* gnatlink.adb (Process_Args): Accept multiple switches for --LINK.
(Usage): Adjust.
* gcc-interface/Makefile.in (GCC_LINK): Remove $(ADA_INCLUDES).
(common-tools): Pass $(CC) as --GCC= and $(GCC_LINK) as --LINK= in
the invocations of $(GNATLINK).

gnatlink: error when calling /usr/bin/g++
../gcc-interface/Makefile:2212: recipe for target 'common-tools' failed
note how we link with the host compiler but pass it -B../../
Removing -B../../ fixes the issue. In PR81878 the issue was we needed to
use the host libstdc++ which is fixed now by using the host CXX to link
but passing -B../../ is obviously broken - it happens that ../../specs
exists (for whatever reasons?!) and that is picked up by the link.
specs is re-generated when I remove it and try continuing:
make[2]: Entering directory '/home/abuild/rguenther/obj/gcc'

mv tmp-specs specs
: > tmp-libgcc.mvars
by
# Dump a specs file to make -B./ read these specs over installed ones.
$(SPECS): xgcc$(exeext)
$(GCC_FOR_TARGET) -dumpspecs > tmp-specs
mv tmp-specs $(SPECS)
and in the end
# List of things which should already be built whenever we try to use xgcc
# to compile anything (without linking).
GCC_PASSES=xgcc$(exeext) specs
removing 'specs' here fixes the issue.
