the new testcase FAILs on Solaris/x86 with /bin/as:
+FAIL: g++.dg/opt/pr83252.C -std=gnu++11 execution test
+FAIL: g++.dg/opt/pr83252.C -std=gnu++14 execution test
+FAIL: g++.dg/opt/pr83252.C -std=gnu++98 execution test
ld.so.1: pr83252.exe: fatal: pr83252.exe: hardware capability (CA_SUNW_HW_2)
unsupported: 0x80 [ BMI2 ]
Inside gcc.target/i386, clearcap.exp takes care of that.
