[Buildroot] [PATCH] arch: add missing 'string' declaration to BR2_LD_TARGET_EMULATION

[Arnout Vandecappelle (Essensium/Mind)]

Commit dc6f4c8 forgot to give a type (string) to the newly introduced
BR2_LD_TARGET_EMULATION symbol.

Possibly it was intended to be a "global" symbol like
BR2_GCC_TARGET_ABI where the declaration is in arch/Config.in and not
in the arch-specific Config.in. However, in this case, the symbol is
only defined/used for MIPS so there is no "global" declaration.

Without this, Kconfig gives a warning:
arch/Config.in.mips:87:warning: config symbol defined without type
