Subject: [PATCH] Makefile: drop -nostartfiles

In commit 0f3e61c9dd48fd8b4248ce4672c044c2562e4de1 ("Use ld instead of
gcc for linking "), we started using ld instead of gcc for the link
step. This worked fine for a while, but recent versions of ld no
longer accept the -nostartfiles option, causing the build to break:

Error: unable to disambiguate: -nostartfiles (did you mean --nostartfiles ?)

In fact, -nostartfiles was passed to gcc prior to
0f3e61c9dd48fd8b4248ce4672c044c2562e4de1, but it is not a ld
option. It is only by luck that it was accepted and ignored by older
ld versions. Since this option is useless when calling ld directly, we
can simply drop it.
