* Problem
Steps:
1) build adt-installer and extract

2) modify adt_installer.conf, config a valid YOCTOADT_REPO, and modify
opkg/conf, config a valid src url. The valid src url is:
http://adtrepo-dev.yoctoproject.org/1.4+snapshot-4ecdc62a74cb4b5d0431d783a
ab5ee266baf833d-stage/master_under_test/

3) run "./adt_installer" to install the adt to the default location.

4) when the installation finish, run "source /opt/poky/1.4+snapshot/envir
onment-setup-armv5te-poky-linux-gnueabi"

5) try to compile iptables-1.4.15. When run "autoreconf -fi", will get the
following errors:
...
Perl lib version (5.14.3) doesn't match executable '/opt/poky/1.4+snapshot
/sysroots/x86_64-pokysdk-linux/usr/bin/autom4te' version (v5.14.2) at /opt
/poky/1.4+snapshot/sysroots/x86_64-pokysdk-linux//usr/lib/perl/5.14.3/Con
fig.pm line 60.
...

6) The host's perl version is v5.14.2, sdk's perl version is v5.14.3

* Analysis
This is because most of the autotools' scripts use the "#!/usr/bin/perl -w"
which is host perl, but the gnu-configize uses "#! /usr/bin/env perl" which
invokes the perl wrapper in the SDK, and the wrapper will set the PERL5LIB to
the SDK which causes the mismatch.

* Solution
We can make all the perl scripts to use the host perl or the SDK perl to
fix this problem.

Similar issue has been fixed in populate_sdk_base:
