Re: [PATCH] Fix ld-cdtest if CFLAGS contains -fexceptions

Surely this is the wrong solution.  Surely ld_compile ought to prepend 
$CFLAGS rather than append it, so that the individual linker tests can 
override command line switches like -fexceptions.

ie if the cdtest.exp wants to use -fno-exceptions then it should be 
allowed to and we should not be trying to work around this by restoring 
the exception handling library to the linker command line.
