Hi, I hope this is the correct place to send this.
I have setup distcc in my network. Most of the hosts are i686, but one of them
is x86_64. I wish to distribute tasks to the i686 machines from the x86_64
machine. This involves installing a cross compiler on the i686 machines for
x86_64 tasks. Crossdev is overkill for this - I don't actually _need_ glibc
and the like on the client machines for a simple distcc environment. It
really adds to the upgrade time when emerge sync; emerge worlding.
The attached patch makes gcc *only* generate the compilers - no libstdcc++, no
libgcc, nothing else - this is all you need for distcc. Likewise, compiling
gcc with this patch needs only binutils - no linux-headers, and no glibc.
I was considering patching the gcc ebuild to add a new option - e.g. "minimal"
to apply this patch - but I've no idea if you would be interested in this
feature. Please let me know if you are, and I'll develop it further if so.
