Actually this doesn't work even without my patch series?
i.e., without my patch series,
1) I "bitbake perl-native" in /poky.git/build/;
2) mv /poky.git/build /poky.git/build.bak;
3) in /poky.git/build2/, modify the conf/local.conf to set SSTATE_MIRRORS to
point to /poky.git/build.bak/sstate-cache/, and "bitbake sgmlspl-native" would
fail in do_compile:
"Can't locate ExtUtils/Command.pm in @INC (@INC contains:
/poky.git/build/tmp/sysroots/i686-linux/usr/lib/perl/5.12.3
/poky.git/build/tmp/sysroots/i686-linux/usr/lib/perl/5.12.3
/poky.git/build/tmp/sysroots/i686-"linux/usr/lib/perl/5.12.3"
Is this an existing bug?
