weird LD definition in src/Makefile

[Paul Jarc]

A while ago I posted that the Emacs build system was defining LD=ld in
src/Makefile on my unusually configured GNU/Linux system.  Various
things have changed on my system since then, and now I get
"LD=$(CC) -nostdlib", which still causes problems (Emacs doesn't know
where my libc is, but gcc does). I'm not very familiar with Emacs's
build system, but I think my system ought to use ORDINARY_LINK.
src/s/gnu-linux.h doesn't mention any of ORDINARY_LINK,
COFF_ENCAPSULATE, or LINKER, so how is it decided what to use?  What's
the relationship/difference between Makefile.c and Makefile.in?  I
noticed some mention of LINKER_WAS_SPECIFIED; can I specify a linker
somehow?  But even if I did, I guess STARTFILES might not match if the
guessed linker is wrong.  I have to arrange for the guess to be right.
But what information is the guess based on?
