Subject: gcc: define _REENTRANT for OpenRISC when -pthread is passed
X-Git-Tag: basepoints/gcc-13~1317

gcc: define _REENTRANT for OpenRISC when -pthread is passed

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.
