Re: Consistently include Makeconfig after defining subdir

[Stefan Liebler <stli at linux dot vnet dot ibm dot com>]

I cannot build glibc on S390 due to failure:
In file included from ../sysdeps/gnu/unwind-resume.c:19:0:
../sysdeps/gnu/unwind-resume.c: In function 'init':
../sysdeps/gnu/unwind-resume.c:35:27: error: 'LIBGCC_S_SO' undeclared 
(first use in this function)
   handle = __libc_dlopen (LIBGCC_S_SO);

LIBGCC_S_SO is defined in gnu/lib-names.h,
which will be generated due to Makeconfig:
# Generate the header containing the names of all shared libraries.
# We use a stamp file to avoid unnecessary recompilations.
before-compile += $(common-objpfx)gnu/lib-names.h

After moving "include ../Makeconfig"  directly under "subdir := csu" in 
csu/Makefile, the variable before-compile is now overwritten by
"before-compile = $(objpfx)version-info.h".

I´ve tested this Patch on S390.

Bye
