x86/boot: Avoid warning for zero-filling .bss
The latest binutils are warning about a .fill directive with an explicit
value in a .bss section:
arch/x86/kernel/head_32.S: Assembler messages:
arch/x86/kernel/head_32.S:677: Warning: ignoring fill value in section `.bss..page_aligned'
arch/x86/kernel/head_32.S:679: Warning: ignoring fill value in section `.bss..page_aligned'
This comes from the 'ENTRY()' macro padding the space between the symbols
with 'nop' via:
.align 4,0x90
Open-coding the .globl directive without the padding avoids that warning,
as all the symbols are already page aligned.
