[Buildroot] [git commit] at91bootstrap3: make sure AT91BOOTSTRAP3_KCONFIG_FILE is always defined

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=7a03f0c89dc76c174bb3f848a9d4b22f13b889c9
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For some (silly?) reason, the kconfig-package infra always wants
<pkg>_KCONFIG_FILE to be defined. So let's do like barebox does: use a
temporary AT91BOOTSTRAP3_SOURCE_CONFIG variable, and assign it to
AT91BOOTSTRAP3_KCONFIG_FILE. This way, the latter is always defined,
even if to the empty value.
