[Buildroot] [git commit master] Makefile.autotools.in: fix libtool patching

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=073af428efc21d7717c003e93a098d0767de3b0c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Fixes two issues with libtool patching:

- It seems like the default value for <package>_LIBTOOL_PATCH only gets
  set AFTER the ifdef check, so the conditional was never taken. Fix it
  by instead checking that it isn't explicitly set to not do the patching
  instead.
- The $i in the libtool patching for loop needed an extra level of escaping
  to work.
