PATCH: [configure,FreeBSD] Default FreeBSD to ELF format

[Gerald Pfeifer]

Until a few days ago, FreeBSD -CURRENT (the equivalent to our mainline) 
featured a program /usr/bin/objformat that would print "elf" on modern ELF 
systems.

Since this program was removed after a deprecation period of half a 
century :-), GCC now falls back to a.out format, at least in how we
name libraries.

The patch below addresses this by defaulting to "elf" instead of "aout"
in case /usr/bin/objformat is not present.

If desired, I can go for the full change of ripping out support for 
anything but elf on FreeBSD, but at least the minimal patch below I'd
like to commit rather sooner than later.

Okay for mainline, 4.2, and 4.1?
