cc65: fix HEAD install; gcc.mak no longer exists.

The `-f make/gcc.mak` option is still required for the latest stable
release, but `make/gcc.mak` was made unnecessary and removed in cc65
commit 9fece990bea6525bec5afd8b60d1c731a4d13839 in 2013, so providing
that option for HEAD builds causes an error.

Closes #34639.

curl: libressl support

New ground has been broken. New seeds have been sowed, etc etc. This
makes the necessary changes to LibreSSL and cURL to enable the latter
to be built with the former. This has been supported upstream for the
last 3 months, and cURL officially supports LibreSSL
[now](http://daniel.haxx.se/blog/2014/08/05/libressl-vs-boringssl-for-cu
rl/) and [has done](http://curl.haxx.se/changes.html) since 7.38.0. A
recompile of LibreSSL and cURL is necessary if you wish to adopt this
locally, but the dependents of cURL should not need to be recompiled.
