[OE-core] [PATCH v2] perl: Allow perl to cross build and native build in a directory named "t"

[Jason Wessel]

If any directory in leading up to your tmp directory has the name "t"
perl will fail to build with a very cryptic error shown below:

pod/buildtoc: no pods at pod/buildtoc line 305.
make[1]: *** [pod/perltoc.pod] Error 255

This is a result of the perl file checking making an assumption
that it is only looking at files and directories with in the perl
source directory.  This assumption fails with the way bitbake
sets up perl to properly cross compile.

+Upstream-Status:Pending
+
+Perl cannot cross build in a path containing a directory that has the
+name of "t".  As an example, you can make the perl build fail with
+"mkdir -p /tmp/build/t", go to the directory, unpack the sources,
+configure and cross build.
+
+You get an error like the following:
+    pod/buildtoc: no pods at pod/buildtoc line 305.
+    make[1]: *** [pod/perltoc.pod] Error 255
+
+The fix is to strip off the top directory that you are building in and
+then execute all the same logic as before against the path relative to
+the build directory.
