[PATCH] kbuild: fix false section mismatch warning referring to .init.text.2

[Sam Ravnborg]

The following section mismatch warning are false:
WARNING: vmlinux.o(.text.head+0x247): Section mismatch: reference to .init.text.1:start_kernel (between 'is386' and 'check_x87')

The problem was that modpost did not see a section named
".init.text.1" as an init section and thus it warned.

This patch fixes this so we no loneg see this warning.
Thanks to report from: Toralf Förster
