Hi Jonathan,

Currently this is shown when building libstdc++ on Solaris:

-lrt: open: No such file or directory

The error comes from the make_sunver.pl script which tries to open each
of its arguments. The arguments are passed by this make rule:

        perl ${glibcxx_srcdir}/scripts/make_exports.pl \
          libstdc++-symbols.ver \
          $(libstdc___la_OBJECTS:%.lo=.libs/%.o) \
         `echo $(libstdc___la_LIBADD) | \
            sed 's,/\([^/.]*\)\.la,/.libs/\1.a,g'` \
         > $@ || (rm -f $@ ; exit 1)

The $(libstdc___la_LIBADD) variable includes $(GLIBCXX_LIBS) which
contains -lrt on Solaris.

This patch adds another sed script to filter -l arguments from the echo
command. In order to reliably match ' -l[^ ]* ' the echo arguments are
quoted and a space added before and after them. This might be overkill
just to remove -lrt from the start of the string, but should be robust
in case other -l arguments are added to $(GLIBCXX_LIBS), or in case the
$(libstdc___la_LIBADD) libraries are reordered.

libstdc++-v3/ChangeLog:

        * src/Makefile.am (libstdc++-symbols.ver-sun): Remove -lrt from
        arguments passed to make_sunver.pl script.
        * src/Makefile.in: Regenerate.

Tested sparc-solaris2.11. Rainer, does this look OK?

it does, but let me give it a try with both GNU sed and Solaris sed: we
had too many weird issues with the latter ;-(

I think the machine I tested on (gcc211 in the compile farm) only has
Solaris sed in the PATH, and it works there.

I did try to use "-l ?[[:alnum:]]+" but Solaris sed only supports BREs
(as POSIX requires) and there doesn't seem to be an equivalent of the
GNU sed -E option to use EREs.
