>Description:
Many ports fail to detect libpthread (because it is still non-existant on
FreeBSD). Therefore provide an easy way for port maintainers to 
s/-lpthread/${PHTREAD_LIBS}/ in the ports configure script.

The setting can be used like this
USE_PTHREAD_HACK=	yes
or
USE_PTHREAD_HACK	file1 file2 file3

Which will apply the substitution on configure or file1, file2 and file3 
respectively. 

Note: This can probably be made an no-op, once libpthread hits the tree.
Or one could set PTHREAD_LIBS to -lthr (or whatever that 1:1 thread
library will be called)
