The text display code used in the Risc PC kernel image decompression code uses arch/arm/boot/compressed/font.c, which includes lib/fonts/font_acorn_8x8.c, which further includes <linux/font.h>. Since commit97df896024("lib/fonts: Provide helpers for calculating glyph pitch and size") <linux/font.h> contains inline functions that require __do_div64, which is not linked into the ARM kernel decompressor. This makes Risc PC zImages fail to build. Resolve this issue by defining the BOOTLOADER symbol and use it to avoid a static declaration of the acorndata_8x8 symbol. That way it can be referenced by the arm bootloader, and other static math functions and symbols (like __do_div64) stay static and don't get unneccesary included in the ARM kernel bootloader decompressor object file.
