This allows setting flags for PaX on select binaries. Two new variables
are introduced for packages: NOT_PAX_ASLR_SAFE and NOT_PAX_MPROTECT_SAFE.
They both expect a list of binaries are known to not support PaX ASLR
and/or PaX MPROTECT, respectively.

with what packages such as multimedia/ffmpeg2 expect, and as so few
packages have texi2html in USE_TOOLS it may be causing more problems
that it is worth to save a few dependencies. PR#51113.
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
problems that are fixed by using the pkgsrc version, and no platform
other than Cygwin tries to use a native version.
Consensus is that due to the limited impact and clear benefit this is
ok to go in during the freeze despite being an infrastructure change.

XXX: if {aclocal,automake}-${latest_version} is really required by somewhere,

get rid of such dependencies and use builtin perl.
