Removing primlib files from libclasspath?

[Dalibor Topic]

Hi everyone,

after merging in libclasspath into Kaffe, primlib's missing LINK_* 
functions broke static builds for riscos. I tried to figure out what 
primlib does briefly, and gave up rather quickly as the files in 
native/jni/classpath/primlib.[ch] seem to be rather void of explanatory 
comments, unfortunately.

Grepping a bit around, it seems that it is unused in GNU Classpath, 
except for a single test, so I'd like to propose removing the primlib 
files from the sources along with the test. The files have seen just 
cosmetic and warning cleanup patches since their introduction.

CC:ing Brian as he introduced them into GNU Classpath.

cheers,
