From: Bernd Kuhls <bernd.kuhls@t-online.de>
The detection of pthread support fails on OpenRISC unless _REENTRANT
is defined. Added the CPP_SPEC definition to correct this.
gcc/ChangeLog:
PR target/94372
* config/or1k/linux.h (CPP_SPEC): Define.

This was brought up on the buildroot list and somehow I missed it. Sending it
now. I plan to commit soon.
