Without this fix, building mesa-demos with the glew
PACKAGECONFIG will result in errors like the below
being logged in tmp/work/*/mesa-demos/*/build/config.log:
configure:16529: checking for GLEW
configure:16536: $PKG_CONFIG --exists --print-errors "glew >= 1.5.4"
Package @requireslib@ was not found in the pkg-config search path.
Perhaps you should add the directory containing `@requireslib@.pc'
to the PKG_CONFIG_PATH environment variable
Package '@requireslib@', required by 'glew', not found
configure:16539: $? = 1
