Log:
[ASAN] Fix fputs interception for 32-bit macOS

On 32-bit macOS, "_fputs$UNIX2003" is called instead of "fputs" and the
"fgets_fputs" test fails. Apparently previous versions still passed the
test due to the internal implementation calling "strlen", but that does
not seem to be the case with macOS 10.13.3. Fixes r334450.
