Fixed according to your suggestion.  Thanks for the review!

I noticed one more problem: target-specific exports are supported since
GNU make 3.81 only, but GCC only requires 3.80.  Luckily nothing besides
install-sh uses STRIPPROG, and install-sh tests for non-empty rather
than unset variable for its semantics, so we can export the variable
from gcc/Makefile.in.  The gcc/ part of the final patch is shown below,
the rest as in <http://gcc.gnu.org/ml/gcc-patches/2010-11/msg00192.html>.

I've committed the whole patch to GCC and src now.

Cheers,
Ralf

PR other/46202: implement install-strip.

gcc/:
	PR other/46202
	* Makefile.in (install_sh, INSTALL_STRIP_PROGRAM): New
	variables.
	(AR_FOR_TARGET, RANLIB_FOR_TARGET, STRIP_FOR_TARGET): Fix
	shell quoting.
	(STRIP_FOR_TARGET): Look for in-tree strip under name strip-new.
	(install-strip): New target.
	(STRIPPROG): New variable, exported if STRIP is set.
	* doc/install.texi (Final install): Minor markup and code style
	fixes.  Document install-strip target.
