[gentoo-lisp] gcl-2.6.10

Hello *,

I've just committed gcl-2.6.10 (keyworded ~amd64 and ~x86). It compiles 
maxima on both arches, maxima tests run fine - no unexpected errors.

The ebuild may have some rough edges, it's largely written from scratch. 
But I think it's OK for ~arch - it needs testing, and nobody will test it 
while it's hard-masked. So, I propose:

1. In profiles/package.mask, mask only <dev-lisp/gcl-2.6.10; let 2.6.10 be 
unmasked.

2. In profiles/arch/{amd64,x86}/use.mask unmask the USE flag gcl (I 
suppose I have to ask these arch teams to do it, after 1 is completed).

Opinions?
