Arm host configure tweaks

The attached patch contains a couple of tweaks to the configure for arm hosts.

-fno-omit-frame-pointer forces gcc to generate the standard prologue/epilogue as required by dyngen. I think this was the default for older GCCs.

It also relaxes the patterns used to recognise arm hosts. In particular 'uname -m' reports "armv5tel" under qemu :-)
