>Description:
	
	- building a cross-gdb on a linux host fails because the
	  main gdb Makefile generated by config.status is broken
	- config.status uses sed to comment out NATDEPFILES
	- some hosts have multiline NATDEPFILES declarations which
	  are not correctly commented out:  the continuation line
	  is not commented out
	- affected hosts are: 
	  alpha/alpha-linux alpha/alpha-osf2 alpha/alpha-osf3
	  arm/linux i386/i386dgux i386/i386sco5 i386/i386sol2
	  i386/i386v4 i386/i386v42mp i386/linux i386/ncr3000
	  ia64/linux m68k/linux m68k/m68kv4 m88k/delta88v4
	  mips/irix4 mips/irix5 mips/mipsv4 mips/nbsd
	  powerpc/solaris sparc/linux sparc/sun4sol2
	- the Makefile snippet which contains the NATDEPFILES
	  declaration is included from (on a linux host):
	  gnu/dist/toolchain/gdb/config/i386/linux.mh

nbmake: "/devel/netbsd/current-lvm/obj/tools/toolchain/build/gdb/Makefile" line 353: Unassociated shell command "core-aout.o i386v-nat.o i386-linux-nat.o linux-thread.o lin-thread.o"
nbmake: Fatal errors encountered -- cannot continue

>How-To-Repeat:
	
build cross-gdb on linux host

MKCROSSGDB=yes ./build.sh  -m next68k -t

(also setting ac_cv_header_fts_h=no is probably necessary because
 of toolchain/16138)

>Fix:
	
the following patch fixes the problem
