core: add BR2_HOSTARCH_NEEDS_IA32_COMPILER option
Some bootloaders (such as Grub) need to be built for x86 (i.e IA32) even if the target architecture is x86-64. However, when the target architecture is x86-64, the cross-compiler generated by Buildroot is not able to generate 32 bits code. To solve this, we will rely on the host compiler being a x86 + x86-64 compiler. Therefore, this commit introduces the BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency checking logic to verify that the host compiler is indeed capable of building x86 32 bits code.
