minor patch to ld/emultempl/elf32.em

[Nick Clifton]

Hi David,

: This patch only activates the Linux processing when targeting Linux (and
: makes room for simular processing when targeting FreeBSD).  I created ld
: targeting i686-pc-linux-gnu and did `make check' and things looked OK,
: along with a `make check' on FreeBSD 4.2.

Why is this patch necessary ?  Ie what harm is there in checking
ld.so.conf on non-Linux based systems ?

Cheers
	Nick
