Mention config-list.mk in new port checklist

Mention config-list.mk in new port checklist

[Joseph S. Myers]

I noticed that contrib/config-list.mk was missing from the new-port 
checklist in doc/sourcebuild.texi.  I've applied this patch to add it; 
target triplets covering all config.gcc stanzas for a new port should be 
added to config-list.mk so the port gets covered in all-targets build 
tests (and, of course, it should be tested that a new port does actually 
pass "make all-gcc" with --enable-werror-always using a current native 
trunk compiler to build it - ideally this should be tested for both 32-bit 
and 64-bit hosts).
