I think it has to do with my /bin/sh being the busybox ash. It seems
the ash prefers its built-in version over the one in path. This is
probably due to me having compiled busybox with some option. Sorry
for the confusion.
If I edit linux/Kbuild to reference explicitly /usr/bin/sed (which
is the gnu sed), the compile proceeds ok up to a point where
following happens
(snip)
make -f scripts/Makefile.build obj=arch/x86/vdso
gcc -Wp,-MD,arch/x86/vdso/vdso32/.int80.o.d -nostdinc -isystem

-Iinclude/asm-x86/mach-default -c -o arch/x86/vdso/vdso32/int80.o
arch/x86/vdso/vdso32/int80.S
arch/x86/vdso/vdso32/int80.S: Assembler messages:

make[1]: *** [arch/x86/vdso/vdso32/int80.o] Error 1

Here the problem appears to be that -c is supplied but there is no
source file to compile. The error message certainly is not
helpful. I'll investigate further.

Busybox ash compiled with certain options is the culprit for
this one.

I would wish at least busybox sed be accommodated. Looking at the
sed expression, it seems unnecessarily complicated. I'll try to formulate
a simpler expression that accomplishes the same net result, namely
transforming
->IA32_SIGCONTEXT_ax $44 offsetof(struct sigcontext, ax)
to
#define IA32_SIGCONTEXT_ax 44 /* offsetof(struct sigcontext, ax) # */
It can't be as difficult as
"/^->/{s:^->\([^ ]*\) [\$$#]*\([^ ]*\) \(.*\):#define \1 \2 /* \3 */:;
s:->::; p;}"
