----------------------------+-----------------------------------------------
This ticket aims to implement a gcc wrapper that will change gcc/ld/...
arguments before passing them on to the underlying compiler binaries. The
most current version is at
https://bitbucket.org/vbraun/gcc-wrapper
Right now, the wrappers
* remove any extra rpath that is set
* set the rpath to `$ORIGIN/../lib`. This makes the sage binaries look
for their libraries in `$SAGE_LOCAL/lib` and no `LD_LIBRARY_PATH` hacks
are necessary.
* some gcc optimization settings are removed 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.
TODO:
* Make the underlying ld binary independently configurable - this will
simplify building Sage on Solaris.
