The build crashes at the step of building module-null-sink.la because the build step omits "-lintl"

It seems to be straightforward problem with the ebuild configuration on what I imagine is a minority platform, i.e., uclibc.

If the build step is repeated manually with "-lintl" inserted, the step succeeds.

Reproducible: Always

Steps to Reproduce:
1. emerge -quDN pulseaudio
Actual Results:  
Crucial lines from temp/build.log are:

The build step should succeed.
