autoconf: Adjust shebang lines to remove interpreter path hardcode
If build host perl (and other tools) is old and we use some kind of toolchain to provide recent perl/python/etc to the OE build we still locked to use build host perl due to hardcoded shebang lines in autoconf scripts. Behaviour was observed with Enterprise Linux 6 and devtoolset toolchain from SCL (Software Collections) used to provide recent version of perl (not provided with default buildtools-tarball). Pass /usr/bin/env perl in ac_cv_path_PERL configuration variables for class-native and class-nativesdk. Use patch to autoconf to replace -w option in shebang line with modern way to enable warnings on perl (i.e. "use warnings"). Also add nativesdk-m4 and nativesdk-gnu-config to RDEPENDS to bring runtime dependencies inline with other targets. Note that ac_cv_path_PERL must be valid perl interpreter path since configure will check perl version and Flock implementation. It is not possible currently to use nativeperl from native sysroot because autoconf does not DEPENDS on perl-native (and doing so fails due to circular dependencies). Only possible solution is to overwrite shebangs with nativeperl somewhere at do_install() and update RDEPENDS for class-native. Or add perl symlinks to nativeperl in sysroot. For now it seems good to use perl found by /usr/bin/env from autoconf-native.

+Subject: [PATCH] perl: Replace -w option in shebangs with modern "use
+ warnings"
+
+In some builds we might provide ac_cv_path_PERL as /usr/bin/env perl
+to use newer version of the perl from users PATH rather than
+older from standard system path.
+
+However using /usr/bin/env perl -w from shebang line isn't
+possible because it translates to something like
+/usr/bin/env -w perl and env complains about illegal option.
+
+To address this we can remove -w option from perl shebang
+line and add "use warnings" statement.
