If eglibc (2.1.5) is selected in openwrt instead

of uclibc, transmission package will fail to
build because the function definition exported by the
libtransmission/fdlimit.c is lightly different than
the function definition in fcntl.h that is installed
by eglibc.

To get transmission build to work both with uclibc
and eglibc, fdlimit.c needs to export function
only if the build toolchain uses uclibc.

This fixes also a openwrt bug
https://dev.openwrt.org/ticket/8820

error: conflicting types for 'fallocate64'
fdlimit.c:30:14: note: previous declaration of 'fallocate64' was here
