Hello, 

the files under /usr/lib64 all belong to one package, which is not even
an official on. Deinstalling that package removes also /usr/lib64
itself, and in that case emacs builds fine.

Any reason not to change the configure.in test that sets
HAVE_LIB64_DIR from

if test -d /usr/lib64

to

if test -e /usr/lib64/crtn.o

?

It would have avoided this problem.

Do we always use "crtn.o" in lib64?  Is fo, then it sounds like a good
idea, indeed.

AFAICS, HAVE_LIB64_DIR affects only two files, both in src/m/
(ibms390x.h and amdx86-64.h).

In both cases, all it does is control which directory Emacs expects to
get the files crt1.o, crti.o, and crtn.o from (for START_FILES and
LIB_STANDARD).
