[oe] Compile eglibc for x86 failed.

[Guo Hongruan]

Hi guys,
   I tried to use eglibc as system library for my x86 box, so I modified  
the conf/distro/minimal-eglibc.conf (see below for my changes). But  
compiling eglibc failed with the message "undefined reference to  
`__i686.get_pc_thunk.bx", The following is the raw error information. Who  
can give me some hint.

ccache i586-oe-linux-gcc -march=i586   -nostdlib -nostartfiles -shared  \
                   -Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both  
-Wl,-z,defs -Wl,--verbose 2>&1 |  \

                       -e 's/\. = 0 + SIZEOF_HEADERS;/& _begin = . -
