Makefile.inc: Alloc .bss* sections for "struct" file type 

When the global variable of a "struct" CBFS file is zero (for example,
CB:47696), the binary will appear in the .bss* section in the ELF file
(instead of .data). This results in an empty binary file added to CBFS,
so that file size check will fail when reading it at runtime.

TEST=emerge-asurada coreboot
TEST=Check sdram-lpddr4x-KMDP6001DA-B425-4GB is non-empty in CBFS
BRANCH=none
