Bug description:clang build fails on Travis CI on gmp

Description:
------------
Currently, setting compiler to clang on Travis CI makes the build fail
by not finding gmp.h. This is because gmp.h is stored in
/usr/include/x86_64-linux-gnu/gmp.h on ubuntu, which is handled by this
code in ext/gmp/config.m4:

  MACHINE_INCLUDES=$($CC -dumpmachine)

  for i in $PHP_GMP /usr/local /usr; do
    test -f $i/include/gmp.h && GMP_DIR=$i && break
    test -f $i/include/$MACHINE_INCLUDES/gmp.h && GMP_DIR=$i && break
  done

The problem here is that clang produces not x86_64-linux-gnu but
x86_64-unknown-linux-gnu. Which leads it to missing the file.

https://wiki.debian.org/Multiarch/Tuples
suggests there's option
-print-multiarch but while gcc supports it, looks like clang does not.
