problems with statically linked zlib

[Simonov, Vladimir]

Hi all,

Environment: host - x86_64-unknown-linux-gnu, target - x86_64-unknown-linux-gnu,
gcc - 4.7.2, binutils-2.23.2.

I'd like to build ld and gold with statically linked zlib. libz.a is built in
advance and placed in some directory ($TOOLS_DIR/lib).
The only way I see - 
export CPPFLAGS="-I$TOOLS_DIR/include"
export LDFLAGS="-L$TOOLS_DIR/lib"
and run configure and build. Without above either system zlib.so is used or gold
sources can't find zlib.h.

What is correct way to configure binutils to get zlib linked-in statically?

Thank you in advance
Vladimir Simonov
