gdb configure issue

[David Gordon Hogan]

I am in the process of porting gdb 5.0 to the Plan 9 operating system.
I am cross-compiling on mips-sgi-irix6.5, and my configure command
looks like this:

        ./configure --prefix=$HOME/gnu  --target=i386-lucent-plan9  
--build=i386-lucent-plan9

When I run gmake, I get lots of these:

        /bin/sh: s,^,i386-lucent-plan9-,:  not found
        /bin/sh: s,^,i386-lucent-plan9-,:  not found
        /bin/sh: s,^,i386-lucent-plan9-,:  not found
        [...etc...]

On further examination, the `CC_FOR_TARGET = ...' line (and similar) of the 
Makefile
is broken because it has had its single quotes (and newlines) removed (relative 
to
the original version in Makefile.in).

Why is this happening, and can it be fixed?  It is very annoying.
