You either need to do 'export CC="..."', or type them on the same line as 
the configure invocation, as 'CC="..." ./configure'.

In an earlier thread, I suggested these commands for building it for 
armv6:

export PATH=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:$PATH
export SDK=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk

CC="gcc -arch armv6 --sysroot=$SDK" CXX="g++ -arch armv6 --sysroot=$SDK" \
LDFLAGS="-Wl,-syslibroot,$SDK" ./configure \
--host=arm-apple-darwin --prefix=${HOME}/opencore-amr-iphone \
--disable-shared
make
make install

If building for both armv6 and armv7, you need to build a similar one for 
armv7, too. You can build one single file that you link to in xcode, that 
contains all the architectures with this command:

lipo -create -output libopencore-amrnb.a armv6-version.a armv7-version.a

If you want to build for the simulator, you need to build a version for 
i386, too. This can be done with these commands:

CC="gcc -arch i386" CXX="g++ -arch i386" \
./configure --disable shared \
--prefix=${HOME}/opencore-amr-iphone-simulator
make
make install

Then merge the armv6, armv7 and i386 versions together with lipo, as shown 
above.

The same commands should work for vo-aacenc, too.
