I am trying to cross compile Linux PAM for android in the following way
`#!/bin/sh
# Linux-PAM/build.sh
INSTALL_DIR="`pwd`/out"
export
PATH="android/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin:$PATH"
export CROSS_COMPILER="$PATH:android/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin"
export SYS_ROOT="android/prebuilts/ndk/current/platforms/android-9/arch-arm"
export CC="arm-linux-androideabi-gcc --sysroot=$SYS_ROOT"
export LD="arm-linux-androideabi-ld"
export AR="arm-linux-androideabi-ar"
export RANLIB="arm-linux-androideabi-ranlib"
export STRIP="arm-linux-androideabi-strip"
mkdir -p $INSTALL_DIR
./configure --host=arm-eabi --build=x86_64 --enable-shared --prefix=$INSTALL_DIR LIBS="-lc -lgcc"
make
make install`
The output gives statically built libraries. I want shared libraries. If I compile for linux, it builds shared library by default. But for Android it builds statically. The config.log file has following
configure:3581: arm-linux-androideabi-gcc --sysroot=android/prebuilts/ndk/current/platforms/android-9/arch-arm -v >&5
Using built-in specs.

What is going wrong?
I've had similar problems cross-compiling for Android from the command line. iOS is fun, too. See How To Configure for Android? on the Autoconf mailing list.
I believe host is incorrect. Try:
./configure --build=`./config.guess` --host=arm ...
or
./configure --build=`./config.guess` --host=arm-linux-androideabi ...
If that's not it, can you post the full results from config.log (full relating to the shared object tests, not the whole file).
Sorry I can't help you further. I'm trying the cross-compile of Linux-PAM-1.1.8 on my MacBook (its set up for Android dev), but here's my result:
In file included from pam_modutil_private.h:14:0,
from pam_audit.c:12:
./include/security/pam_modutil.h:53:20: fatal error: shadow.h: No such file or directory
compilation terminated.
make[2]: *** [pam_audit.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
$ pwd
/Users/jwalton/Linux-PAM-1.1.8
$ find . -iname shadow.h
$
I noticed this in the the big long log string:
Target: arm-linux-androideabi
Configured with: /tmp/android-8532/src/build/../gcc/gcc-4.6/configure ...
--disable-shared ...
So shared libraries are disabled, which means you won't be building them.
I made small progress and found that the can_build_shared flag is turned off because it can not find dynamic linker for host type = eabi
configure:9299: checking dynamic linker characteristics
In configure script the check is as following
{ $as_echo "$as_me:${as_lineno-$LINENO}: checking dynamic linker characteristics" >&5
$as_echo_n "checking dynamic linker characteristics... " >&6; }
if test "$GCC" = yes; then
case $host_os in
then there is a list of host_os like darwin, aix... but no swith case for "host_os=eabi"
This is the root cause. Looking for the solution..
