#12703: GLPK fails to build with LTO (`gcc -flto ...`)

------------------------+---------------------------------------------------
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.
