>Description:
after a fresh bootstrap and build of gcc47 on solaris abi=32, building 
meta-pkgs/modular-xorg revealed a serious problem building openssl as a 
dependency of python27 when python itself is a "tool" BUILD dependency instead 
of "yes".
The following error extract:

>How-To-Repeat:
Fresh bootstrap with abi=32
build lang/gcc47
build meta-pkgs/modular-xorg
>Fix:
specific fix unknown, but workaround is the following:
