updating gcc/Makefile.in:s-macro_list sed for make-3.81 in gcc-4.0/gcc-4.1 branches

[Mike Frysinger <vapier at gentoo dot org>]

the new make-3.81 conforms to POSIX rules when it comes to the use of \ in 
single quoted strings ... this breaks the s-macro_list rule in 
gcc/Makefile.in as it splits a single quoted string across two lines with a \ 
and when building with make-3.81 we get this error:
sed: -e expression #1, char 88: unterminated address regex

this has been fixed in trunk/gcc/Makefile.in already, but it looks like the 
fix leaked in rather than being properly documented:
http://gcc.gnu.org/viewcvs?rev=112647&view=rev
http://gcc.gnu.org/ml/gcc-patches/2006-04/msg00097.html

patches attached to fix up gcc 4.0 and 4.1 branches ... i left the ChangeLog 
empty because i dont really care who gets credited
