+Subject: [PATCH] tests: Use FE_UPWARD only if its defined in fenv.h
+
+On ARM, musl does not define FE_* when arch does not have
+VFP, (which is right interpretation), therefore check if
+its defined before using it
+
+Fixes errors like
+
+tests/general/roundmode-pixelstore.c:82:19: error: 'FE_UPWARD' undeclared (first use in this function)
+  ret = fesetround(FE_UPWARD);
+                   ^~~~~~~~~
