Subject: [PATCH] build-sys: fix conftest.c to work on arm
All tests for compiler support were failing with:
/usr/bin/ld: /tmp/ccwnVc2A.o: relocation R_ARM_MOVW_ABS_NC against `a' can not be used when making a shared object; recompile with -fPIC
(cherry picked from commit 0943f4b7b22fb676fcd9ede50f8133bf6d4a270b)
(cherry picked from commit 5f6262c1129e4909e72382bba41fdde036f27eee)
