Tried that. Get exactly the same result with both GCC 4.9 and GCC 5.5

I'm doing this in a pkg_comp1 libkver sandbox which makes setting 
GCC_REQD really hard and I'm wondering if that leads to this side effect 
regardless of compiler.

To be able to do GCC_REQD=4.9 in pkg_comp I'm having to do the following:
1. Do a bootstrap build of gcc 4.9 in a separate sandbox.
2. Install the gcc 4.9 package using INSTALL_PACKAGES
3. Add a mount hook that only adds GCC_REQD=4.9 into mk.conf once the 
base tools are install (cwrappers, digest x11-links etc).

If I don't take these steps the pkgcomp bootstrap fails as it can't 
create the bootstrap environment due to the circular dependency between 
digest and gcc 4.9!

The 6.x machine in question would take forever to build its own packages 
which is why I use the pkg_comp environment.
