release 4.15

Replace -o /dev/null by -o "$tmpc".out in check_link_silent and
check_compile otherwise test will fail with some bugged binutils
(https://sourceware.org/bugzilla/show_bug.cgi?id=19526) since version
4.13 and
https://github.com/rofl0r/proxychains-ng/commit/35a674bdbc294730429a1007c9e7ce01e65b49b5:

checking what's the option to use in linker to set library name ...
cannot find an option to set library name
package/pkg-generic.mk:249: recipe for target '/home/buildroot/autobuild/instance-2/output-1/build/proxychains-ng-4.14/.stamp_configured' failed
