Thanks @mcrute for his great answer, and XCode 5 requirement update I have updated script. Hope it useful for new users.

NOTE: Don't forget to update SDK_VERSION based on your system installation

#!/bin/bash

DEVELOPER=`xcode-select -print-path`

SDK_VERSION="7.1"

mkdir build

function build_lame()
{
    make distclean

    ./configure \
        CFLAGS="-isysroot ${DEVELOPER}/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
        CC="${DEVELOPER}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -arch ${PLATFORM} -miphoneos-version-min=7.0 " \
        --prefix=/Users/mcrute/Desktop/lame \
        --host="arm-apple-darwin9" \
        --disable-shared \
        --enable-static \
        --disable-decoder \
        --disable-frontend

    make -j4
    cp "libmp3lame/.libs/libmp3lame.a" "build/libmp3lame-${PLATFORM}.a"
}

PLATFORM="i686"
SDK="iPhoneSimulator"
build_lame

PLATFORM="armv6"
SDK="iPhoneOS"
build_lame

PLATFORM="armv7"
build_lame

PLATFORM="armv7s"
build_lame
