[Buildroot] [PATCH 1/1] package/avrdude: fix gpio definition, add kconfig option

[Matt Weber]

From: Sam Voss <samuel.voss at rockwellcollins.com>

Fix bug causing '--enable-linuxgpio' to not work
due to a misnamed definition. This patch has been
submitted upstream at https://github.com/kcuzner/avrdude/pull/15.

Add the option to enable linux gpio configure option
in menuconfig.
