New description:
This ticket aims to implement a gcc wrapper that will suitably modify
gcc/ld/... arguments before passing them on to the underlying compiler
binaries. The most current version is at:
https://bitbucket.org/vbraun/gcc-wrapper
and a spkg is here:
http://www.stp.dias.ie/~vbraun/Sage/spkg/gccwrapper-1.0.spkg
Right now, the wrapper
* removes any extra rpaths that are set
* sets the rpath to `$ORIGIN/../lib`. This forces the sage binaries to
first look for their libraries in `$SAGE_LOCAL/lib` and no
`LD_LIBRARY_PATH` hacks are necessary any more.
* removes some gcc optimization settings that are broken on itanium and
gcc 4.4.1. See also #10430.
The wrapper is implemented in pure C++ and does not depend on any Sage
component.
