Bug 836

this is similar to Bug 829 with same error message, but from a different reason:

miniperl is used which is linked to hostperl which is further linked to sysroot/perl5.12.2. Currently we only provide wrapper to the perl binary, instead of perl5.12.2. Here there're two potential issues to be solved:

a) perl5.12.2 is actually exactly same as perl. I'm not sure why there's such a separate binary with version number. Is a symbol link enough? Or else we need a seperate wrapper script for perl5.12.2 too.

b) don't create hostperl symbol link within perl source directory, which breaks the wrapper script. The wrapper script assumes that the wrapper and the real binary are in same sysroot directory (see "dirname $0" in the wrapper script). However when hostperl is created within perl source directory, the real binary can't be found then. Actually perl-native already creates a hostperl link in sysroot. So we don't need another duplication in target perl recipe.

Again you have to remove the build directory which generates sstate packages to expose this issue.
