hi,

The computation if threads should be used by default should not be
done in a user settable variable (PERL5_USE_THREADS), especilly if it
will be deprecated.  Simply set PKG_SUGGESTED_OPTIONS accordingly.

: +.if !empty(PERL5_USE_THREADS:M[yY][eE][sS])
: +PKG_SUGGESTED_OPTIONS= threads
: +.endif

  Use
	PKG_OPTIONS_LEGAY_VARS+=PERL5_USE_THREADS:threads
instead.  PKG_SUGGESTED_OPTIONS should only contain the options enabled by
default and should not be influenced by user settings.  Options
enabled due to legay variables should go into PKG_LEGACY_OPTIONS and
emit a warning, both of which PKG_OPTIONS_LEGACY_VARS does.

						yours,
