[Buildroot] [PATCH] minnowboard_max_defconfig: grub2 needs WCHAR

[Arnout Vandecappelle (Essensium/Mind)]

Since commit 5ffafd2353f5d67 (grub2: bump up version), grub2 needs a
toolchain with WCHAR support. However, the defconfigs that use grub2
were not updated at the time.

Add BR2_TOOLCHAIN_BUILDROOT_WCHAR=y to minnowboard_max_defconfig.

The following other defconfigs also use grub2.

galileo_defconfig: Needs to be updated, but is anyway failing to build
 the kernel and I expect it will be removed.

minnowboard_max-graphical_defconfig: Already selects LOCALE which
 implies WCHAR.

pc_x86_64_bios_defconfig, pc_x86_64_efi_defconfig: already select
 WCHAR because it is needed for eudev.
