New description:
Even the latest upstream version (4.47) fails to build when link-time
optimization (LTO, `gcc -flto ...`) is enabled.
While `configure` shows an error message, it continues normally and
doesn't exit with an error. Only later during the build, a shell syntax
error caused by `libtool` makes the build finally fail.
The solution is to re-autotoolize the package with more recent autotools.
I have an spkg with updated autogenerated files which also upgrades GLPK
within Sage to the latest stable version, 4.47.

=== glpk-4.47.p0 (Leif Leonhardy, March 19th 2012) ===
* #12703: Make GLPK work with LTO (`gcc -flto ...`).
This just involves updating the lib- and autotools files,
but thereby upgrading to the latest version (4.47) shouldn't
hurt either.
Note that the `src/` directory now isn't vanilla, since upstream
hasn't yet fixed the bug (i.e., updated these files).
The "real" source files in contrast of course *are*.
See "Special Update/Build Instructions" above on how to update
the files of a fresh upstream tarball if necessary.
* Cleaned up `spkg-install` and `spkg-check` (and this file ;-)
* Running the test suite now uses `$MAKE` instead of `make` as well.
* `CPPFLAGS` and `LDFLAGS` no longer get overwritten in `spkg-install`.
