This ticket implements a wrapper for the compiler that lets us rewrite
compiler options on the fly. The goal is to fix:
1. Clashes between system and Sage's libraries due to LD_LIBRARY_PATH
abuse.
1. Relocation issues, i.e., "dead" (hard-coded) RPATHs in binaries (shared
libraries and executables) created by Sage, upon moving the installation
(which includes installing a pre-built / binary distribution).
1. Broken compiler versions / tool chains; work around by messing with
(e.g.) optimization flags, depending on the present compiler and its known
issues.
The wrapper is implemented in pure C++ and does not depend on any Sage
component. At the moment it only wraps gcc and does not do anything for
other compilers.

Comment:
I've gitified the ticket without making it a standard package (basically,
Volker's hg patch).
I think should definitely make it optional at least.
And I give positive review to what Volker done, except for maybe not
making the package standard, at least now...
