[gentoo-dev] Add LDFLAGS="-Wl,--hash-style=gnu" to developer profile's make.defaults

[Doktor Notor]

The amount of bugs concerning ebuilds that ignore LDFLAGS suggests
that this would be a good idea, b/c it seems a many maintainers are
completely unaware that their ebuilds do not respect LDFLAGS - so I
guess this needs more visibility.

P.S. If you wonder why this flag then
check /usr/lib/portage/bin/misc-functions.sh ;)
