[poky] Question about apply eglibc configurability to create minimal image

Hi Mark,

I am focus on eglibc itself compilation with disabling all the 
configurable options, right now eglibc can be compiled with disable all 
the configurable options.

But when I build core-image-minimal in a clear new directory, some 
packages build failed and they need eglibc supports, such as

gcc-runtime    depends on     libc-libm
ncurse            depends on    libc-posix-wchar-io libc-posix-clang-wchar
openssl           depends on    libc-inet libc-nsswitch
gettext            depends on    libc-spawn libc-locale-code 
libc-getlogin libc-utmp
...

After enable those options, the image size only decrease from 9.6M  to 
9.4M(qemux86). And the dependencies on eglibc is hard to break, 
something like  libcrypt getlogin(function) can't be breaken.
Could you give me some directions what should I do with eglibc 
configurability?
Thanks a lot!

I made a mistake that try eglibc configurability in a directory which 
has build core-image-minimal, so the packages which depend on eglibc 
didn't rebuild, and I didn't find the dependency before. I am sorry!

Regards,
Kai
