SSLBASE vs. PREFER_PKGSRC=openssl

[Aleksey Cheusov <cheusov%tut.by@localhost>]

A lot of packages use SSLBASE/BUILDLINK_PREFIX.openssl variables in
order to find openssl base directory. These variables are not set
correctly if PREFER_PKGSRC=openssl.

   0 alpine>make show-vars VARNAMES='SSLBASE SSLCERTS'
   /usr
   /etc/openssl/certs
   0 alpine>make show-vars VARNAMES='SSLBASE SSLCERTS' PREFER_PKGSRC=openssl

   /usr/pkg/etc/openssl/certs
   0 alpine>

The following patch (-U12) solves the problem. Do you mind if commit it?
