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.

Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de>

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