Bootstrap failure on powerpc-ibm-aix4.1.4.0 after ppc branch merge

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

	Now that the newppc branch is merged back in, I tried
bootstrapping on powerpc-ibm-aix4.1.4.0.  The first problem I had was
that collect2 couldn't compile in stage1 because of missing functions
normally found in libld.a.  I think x-aix41/x-aix43 used to have
CLIB=-lld in it, but these lines got moved to target files so cross
compiles would work.  Now t-aix43 has the CLIB setting and there is no
t-aix41.  So I created one.  Here's the patch I used to get past this
problem.

Now having done that, I got an error in stage2 when building libgcc2.a:

Here is the backtrace from gdb:

Should I install the CLIB/t-aix41 patch?  Any ideas on the core dump?
