[PATCH]: Fix 2 gas testsuite failures for 68HC11/68HC12

[Stephane Carrez <Stephane dot Carrez at worldnet dot fr>]

Hi!

When I fixed the weak symbols in 68HC11/68HC12 GAS, I introduced a bug
that causes relaxation to be refused for externally visible symbols.
It was due to the fact that I took the M68K check, and for M68K, the relaxation
must not be made because symbols can be overridden by shared libraries.
Since 68HC11/68HC12 do not have shared libraries, this is not necessary.

I committed the following patch to fix this in the trunk. 
I'll try to put it in the binutils-2_11-branch too (if I succeed in knowing
how to do that...).

	* config/tc-m68hc11.c (relaxable_symbol): Relax externally visible
	symbols because there is no support for shared libraries and these 
	symbols can't be overridden (unless they are weak).
