我喜欢为Android x86模拟器交叉编译Perl。但是在运行配置时出现了PIE（位置无关的可执行文件）错误...基于this和this教程。
规格：
我设置了以下变量：
export ANDROID_NDK=/home/fabian/Android/Sdk/ndk-bundle
export TARGET_ARCH=x86
export ANDROID_TOOLCHAIN=/tmp/toolchain-x86
export SYSROOT=$ANDROID_TOOLCHAIN/sysroot
export TARGETDIR=/data/local/perl
export GCC=i686-linux-android-gcc
export PATH=$PATH:$ANDROID_NDK/toolchains/x86-4.9/prebuilt/linux-x86_64/bin
然后我使用以下命令构建工具链：
$ANDROID_NDK/build/tools/make-standalone-toolchain.sh --platform=android-23 --install-dir=$ANDROID_TOOLCHAIN --toolchain=x86-4.9
并得到这个（正确？）输出：
HOST_OS=linux
HOST_EXE=
HOST_ARCH=x86_64
HOST_TAG=linux-x86_64
HOST_NUM_CPUS=4
BUILD_NUM_CPUS=8
Auto-config: --arch=x86
Toolchain installed to /tmp/toolchain-x86.
然后我启动./Configure命令：
./Configure -des -Dusedevel -Dusecrosscompile -Dtargetrun=adb -Dcc=i686-linux-android-gcc -Dsysroot=$SYSROOT -Dtargetdir=$TARGETDIR -Dtargethost=emulator-5554
得到了这个输出：

You don't have an ELF gcc. I will use dld if possible. If you are
using a version of DLD earlier than 3.2.6, or don't have it at all, you
should probably upgrade. If you are forced to use 3.2.4, you should
uncomment a couple of lines in hints/linux.sh and restart Configure so
that shared libraries will be disallowed.
Disabling ndbm. This will generate a Whoa There message in Configure.

I've tried to compile and run the following simple program:
#include
int main() { printf("Ok\n"); return(0); }
I used the command:
i686-linux-android-gcc -o try -O2 -DOVR_DBL_DIG=14 --sysroot=/tmp/toolchain-x86/sysroot --sysroot=/tmp/toolchain-x86/sysroot try.c -lm -lc
/home/fabian/Desktop/Testimages/perl-5.22.1/Cross/run-adb-shell ./try
and I got the following output:
The program compiled OK, but exited with status 134.
You have a problem. Shall I abort Configure [y]
Ok. Stopping Configure.
好的我必须设置标志
修改config.sh以启用PIE支持。将“-fPIE”附加到ccflags和 “-fPIE -pie”到ldflags。然后重新运行configure以确保这是 应用
但是perl文件夹中没有config.sh，所以我尝试了这个./Configure命令：
`./Configure -des -Dusedevel -Dusecrosscompile -Dtargetrun=adb -Dcc=i686-linux-android-gcc -Dsysroot=$SYSROOT -Dtargetdir=$TARGETDIR -Dtargethost=emulator-5554 -Dccflags='-fPIE' Dldflags='-fPIE -pie'`

我错过了什么吗？
