powerpc-rtems-gcc @4.2.3 fails to build

[ozaktash@…]

powerpc-rtems-gcc @4.2.3 fails to build due to 2 reasons:

1-) texinfo5: The file main.log_makeinfo5 contains the related error log. One workaround is to use makeinfo from OS X Yosemite which has the version 4.8. Passing parameters below to macports invocation should mitigate this problem: build.args="MAKEINFO=/usr/bin/makeinfo" destroot.args="MAKEINFO=/usr/bin/makeinfo"

2-) clang: The file main.log_makeinfo4 contains the related error log. A workaround is to use gcc (gcc49 works, but I think any gcc4x should work). Passing parameter below to macports invocation should mitigate this problem: configure.compiler=macports-gcc-4.9

Two workarounds combined: build.args="MAKEINFO=/usr/bin/makeinfo" destroot.args="MAKEINFO=/usr/bin/makeinfo" configure.compiler=macports-gcc-4.9

I am also attaching a patch file proposal that combines the two workarounds and depends on gcc49.
