Support for adding libraries compiled with the alternative gcc (2 vs.

Browse Source 
4). One has to have a (fully configured) "generated" directory for the
alternative gcc and specify it using the new option
"--alternative-gcc-output-dir" when configuring the main build.
Additionally the build variable HAIKU_ADD_ALTERNATIVE_GCC_LIBS has to be
set to "1".

If that has been done, when building the image a sub-jam is invoked that
generates the alternative libs and zips them. The main-jam unzips them
into the correct directory in the image. Note that the JAM build
variable has to be set when using a jam executable not invoked by "jam".

Tested with gcc 2 NetPositive, Pe, and FireFox under gcc 4 Haiku, and
with a few of the standard gcc 4 Haiku apps under gcc 2 Haiku. Seems to
work fine so far.
