Yes, arm-linux-gnueabi implies the EABI with -mfloat-abi=soft or
-mfloat-abi=softfp, while arm-linux-gnueabihf implies -mfloat-abi=hard.
I amend the commitlog a little, and push the patch below in.

Subject: [PATCH] Find arm-linux-gnueabi(hf)?-gcc in compile

GCC for arm-linux has different names on different distros.  It is
arm-linux-gnu-gcc on fedora.  Debian/Ubuntu has arm-linux-gnueabihf-gcc
and arm-linux-gnueabi-gcc.  So when I run gdb.compile/ tests on arm-linux,
I get,

(gdb) compile code -- ;
Could not find a compiler matching "^arm(-[^-]*)?-linux(-gnu)?-gcc$"

This patch extend the regexp to match both arm-linux-gnu-gcc and
arm-linux-gnueabihf-gcc.
