arm: Define with_float to hard when target name ends with hf
On arm, the --with-float= configure option is used to define include
files search path (among other things). However, when targeting
arm-linux-gnueabihf, one would expect to automatically default to the
hard-float ABI, but this is not the case. As a consequence, GCC
bootstrap fails on an arm-linux-gnueabihf target if --with-float=hard
is not used.
This patch checks if the target name ends with 'hf' and defines
with_float to hard if not already defined. This is achieved in
gcc/config.gcc, just before selecting the default CPU depending on the
$with_float value.
