Anyone having problems with libasn1 choking because ASN1_COMPILE is
somehow not getting set?  mk.conf says:
MKTOOLS=yes
TOOLDIR=/usr/src/tool
USE_NEW_TOOLCHAIN=yes
USETOOLS=YES

bsd.own.mk looks to me like it should be unconditionally setting ASN_COMPILE,
but when make tries to refer to ${ASN1_COMPILE}, it expands to empty, so the
build fails.
