+Subject: [PATCH] build: find pre-built heimdal build tools in case of embedded
+ heimdal
+
+This patch fixes the case of finding asn1_compile and compile_et for
+building embedded heimdal, by setting
+--bundled-libraries='!asn1_compile,!compile_et' as configure flags.
+
+The Heimdal build tools compile_et and asn1_compile are needed *only*
+if we use the embedded heimdal (otherwise we don't build heimdal and
+use headers that have been generated by those tools elsewhere).
+
+For cross-compilation with embedded heimdal, it is vital to use host build
+tools, and so asn1_compile and compile_et must be supplied and not
+built. One way of doing this would be to set the COMPILE_ET and
+ASN1_COMPILE env vars to the location of supplied binaries. Another way,
+which is more commonly used, is to exclude asn1_compile and compile_et
+from bundled packages via the switch
+-bundled-libraries='!asn1_compile,!compile_et'. When this is done,
+the build script searches the path for those tools and sets the
+ASN1_COMPILE and COMPILE_ET vars accordingly. (this is admittedly
+kind of a round-about way of doing things but this has become the
+de-facto standard amongst embedded distro builders).
+
+In commit 8061983d4882f3ba3f12da71443b035d7b672eec, this process of
+finding the binaris has been moved to be carried out only in the
+system heimdal case. As explained above, we only need these tools,
+and hence the check, in bundled mode.
