First part of minor dropbear package cleanup - this part lets the
package build as a normal user

+ don't refer to MAKEFLAGS outside of pkgsrc/mk
+ add comments to patch files
+ use BSD_INSTALL_* definitions in the build Makefile
+ re-order some parts of the pkgsrc Makefile
+ use pkgsrc definitions for CFLAGS.${OPSYS} rather than conditionals

XXX - TO DO - fix the xauth issue here
pkg/48500:  add a hack on NetBSD/alpha to add the gcc compiler flag
	    -fno-tree-ter, removing the alignment warnings printed by the
	    NetBSD/alpha kernel when perl was executed.

	    bump PKGREVISION
Mark some stuff not available for python and use versioned_dependencies.mk,
so that pbulk can finish a scan again.
Use standard comments.
