May be better is to rewrite current test to be more portable.
According to specs file on linux gcc with -pthread  add pthread library 
and define _REENTRANT.

AX_PTHREAD is an existing macro distributed under GPL.  May be current 
test could be replaced to use this macro if there is no license issue.

What could be used, on solaris for pthread support, instead link with 
library ?
If compiler is gcc is enough to set -pthreads as compiler flag (CFLAGS) 
? What about other compilers (Sun C? ) ?

No.
Please, test for feature with use functional tests instead to hard code 
a feature based on os version.
