Hm, it looks like Jerome never got back to work on these changes... let 
me try to
pick up the ball and run with it.

Haiku (and BeOS for that matter) has pthread support built into its core 
libroot.so.

No need for -lpthread, all applications can assume its presence. Things 
that link -lpthread actually fail due to a non-existant libpthread...  
*however* as i'm typing this i'm being told we recently implemented a 
dummy static libpthread.a to try and appease assumptions about -lpthread 
existence.... so i'll remove the pthread checks :-)
