Build log and `emerge --info` output for bochs-2.7.

When choosing the VGA display library to use, I expect to be able to use "x" since I compiled bochs with the "X" USE flag. However, I am only able to choose from nogui and term. Discovered on AMD64.

Build log and output of `emerge --info bochs` attached. Judging by the former, it seems that the ebuild fails to install the plugin files.

I managed to reproduce the problem, looks like its build system is old enough to trip on recent enough glibc.

I opened to see if upstream is amenable to the idea.

Workaround patch

The attached patch works around this issue by recognizing x86_64 as an official Linux CPU architecture with dynamic linking.

Caution: I have no idea what I am doing, this hopefully does not break anything else.

The real fix would be to modernize the build system - either by upgrading autotools or switching to something else (this is tracked in the upstream issue).
