PATCH: Allow building on armv4l-unknown-linux-gnu

[Manfred Hollstein]

Hi there,

The current t-linux  file for ARM sets up  multilibs for hard and soft
float.  AFAIK, all  Linux systems including the  ARM one use either an
FPU or, if  that's not available, an  FP emulator which makes using FP
instructions transparent to the user.

Building current sources  from CVS fails  when libgcc/crtbegin/end are
built   for   the   soft-float     version;  the   reason    is   that
/usr/lib/crt{i,n}.o were built using  hard-float flags, which ld  then
in turn complains about.

I'm not sure how others succeeded  to build this configuration without
a similar patch.

OK to install?

Cheers, manfred
