Fix for "Unsupported relocation type" ?

["Nathaniel W. Filardo" <nwf@xxxxxxxxxxxxxx>]

Unsure of the proper place to send this, I'll post it here and see what 
happens.

There have been a few reports of "Unsupported relocation type" with type 
R_386_TLS_TPOFF32.  This patch fixes the problem locally enough to let 
lang/ruby18 (with errno definitions removed) build successfully where it 
could not before.  If this was already in the works, sorry for stepping on 
toes.
