As noted in checkin:
a3e854d95 x86, relocs: Workaround for binutils 2.22.52.0.1 section bug
ld version 2.22.52.0.[12] can incorrectly promote relative symbols to absolute, if the output section they appear in is otherwise empty.
Since checkin:
6520fe55 x86, realmode: 16-bit real-mode code support for relocs tool
we actually check for this and error out rather than silently creating a kernel which will malfunction if relocated.
Ingo found a configuration in which __start_builtin_fw triggered the warning.
Go through the linker script sources and look for more symbols that could plausibly get bogusly promoted to absolute, and add them to the whitelist.
In general, if the following error triggers:
Invalid absolute R_386_32 relocation: <symbol>
... then we should verify that <symbol> is really meant to be relocated, and add it and any related symbols manually to the S_REL regexp.
Please note that 6520fe55 does not introduce the error, only the check for the error -- without 6520fe55 this version of ld will simply produce a corrupt kernel if CONFIG_RELOCATABLE is set on x86-32.

H A D | Makefile | 24cc7fb69a5b5edfdff1d38c6a213d6a33648829 Thu Sep 20 09:28:45 CDT 2012 Jeff Mahoney <jeffm@suse.de> x86/kbuild: archscripts depends on scripts_basic
While building the SUSE kernel packages, which build the scripts, make clean, and then build everything, we have been running into spurious build failures. We tracked them down to a simple dependency issue:
$ make mrproper CLEAN arch/x86/tools CLEAN scripts/basic $ cp patches/config/x86_64/desktop .config $ make archscripts HOSTCC arch/x86/tools/relocs /bin/sh: scripts/basic/fixdep: No such file or directory make[3]: *** [arch/x86/tools/relocs] Error 1 make[2]: *** [archscripts] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2
This was introduced by commit 6520fe55 (x86, realmode: 16-bit real-mode code support for relocs), which added the archscripts dependency to archprepare.
This patch adds the scripts_basic dependency to the x86 archscripts.
