Fixed arm-linux build problems

2004-06-27  Dalibor Topic  <robilad at kaffe.org>

        * config/arm/linux/sigcontextinfo.h:
        Fixed compilation problems with not matching
        sigcontext and k_sigcontext structs.

        * config/arm/sysdepCallMethod.h:
        (sysdepCallMethod) Removed bogus clobbered
        constraints. Fixes build with gcc 3.4.0.

        * config/arm/linux/armsigctx.h,
        config/arm/linux/kernel-features.h:
        Removed.
