powerpc. No revision bump because packages never built on base-gcc
archs.
diffs and build testing on ppc from cwen@, thanks!
ok jca@ for vulkan-loader diff

DESCR:
An OpenGL and OpenGL ES shader front end and validator.
There are several components:
A GLSL/ESSL front-end for reference validation and translation of
GLSL/ESSL into an AST.
An HLSL front-end for translation of a broad generic HLL into the AST.
A SPIR-V back end for translating the AST to SPIR-V.
A standalone wrapper, glslangValidator, that can be used as a
command-line tool for the above.
