perl: Allow perl to cross build and native build in a directory named "t"
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.
