The RPATH tags allow a binary to tell the dynamic linker what
directories to search for libraries. The so-added paths are
searched into before any other paths.

Only starting with 4.4 does gcc have a -print-sysroot option.
For 4.3 or before, we have to play some tricks:
- ask gcc where libc.so is,
(we expect it in ${sysroot}/usr/lib/libc.so)
- trim /usr/lib/libc.so from the result

Break the library search loop as soon as a match is found.
Previously, if a library was present in different places,
then the last occurence would be returned, when the first
one would have been used at runtime.

Since Subversion 1.6.13 was released, it is no longer possible
to checkout/export to the current working directory using '.'
(eg. "svn co bla://blabla/foo/bar ." no longer extracts the content
of bar into ./ but into ./bar).
Fix this by luring Subversion to extract into "$(pwd)", which has
the advantage of working both with all known versions so far.
At the same time, remove the useless redirection.
No new feature, no newer version, only updates so that
samples can be recalled without anything to set.

I ran into some minor difficulties looking through the build log for a
particular file: I wasn't interested in seeing it unpacked, but only
when it is built or installed. Adding these two levels allows me to
differentiate between those cases.

In case we build the C++ compiler, we have to tell gcc where to put the C++
headers, or else it will try to # put it in prefix/tuple/include, which we
make a symlink to sysroot/usr/include during the build, and that we delete
(the symlink!) after the build, but gcc will not look in sysroot/usr/inlcude
for C++ headers by default.
