There's no need to do that. Try instead:
export PATH=/opt/android-ndk-r8-standalone/bin:$PATH
./configure --host=arm-linux-androideabi [more configure options]
everything else should be found automatically (also libz which is part
of the NDK)

no, unfortunately not; this symbol is part of the NDK - as you found
self already - and I ran into similar issues when I specified too many
paths into the NDK; some googling then suggested to create the
standalone toolchain (as you did already) and to avoid any paths into
that toolchain (-L) and any libs (-l) unless you do really build with
some non-standard stuff ...
see f.e. my autobuilds:
http://curl.haxx.se/dev/builds.html
here I only specify the libs not part of the NDK:
http://curl.haxx.se/dev/log.cgi?id=20120606131527-5060
I try to setup a build shortly with NDK r8 (which I use on another
machine already) + shared, then we might see if that fails ...

hmm, you best bet might be /system/lib since you cant count that the
symlink /lib exists; but AFAIK Android doesnt support versioned .so libs
art all - at least I dont see any *.so.x.y in the firmware images I
examined so far ...;
therefore my suggestion to link statically - if you only have to care
about your one application and have no space issues then why mess with
library paths + the risk that another apps might downgrade your libcurl.so ?
