ncurses 6.5 交叉编译移植到OpenHarmomy

ncurses这个库被很多软件包依赖，比如cpython和htop，笔者将ncurses 6.5 交叉编译移植到OpenHarmomy分享如下

arm 64位交叉编译

# 获取ncurses-6.5源码
wget https://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.5.tar.gz
tar -xvzf ncurses-6.5.tar.gz
cd ncurses-6.5

# 指定oh交叉编译环境
export OHOS_SDK=/root/OpenHarmony/cix_myself_5.0.0/prebuilts/ohos-sdk/linux/12
export AS=${OHOS_SDK}/native/llvm/bin/llvm-as
export CC="${OHOS_SDK}/native/llvm/bin/clang --target=aarch64-linux-ohos"
export CXX="${OHOS_SDK}/native/llvm/bin/clang++ --target=aarch64-linux-ohos"
export LD=${OHOS_SDK}/native/llvm/bin/ld.lld
export STRIP=${OHOS_SDK}/native/llvm/bin/llvm-strip
export RANLIB=${OHOS_SDK}/native/llvm/bin/llvm-ranlib
export OBJDUMP=${OHOS_SDK}/native/llvm/bin/llvm-objdump
export OBJCOPY=${OHOS_SDK}/native/llvm/bin/llvm-objcopy
export NM=${OHOS_SDK}/native/llvm/bin/llvm-nm
export AR=${OHOS_SDK}/native/llvm/bin/llvm-ar
export CFLAGS="-fPIC -D__MUSL__=1"
export CXXFLAGS="-fPIC -D__MUSL__=1"

打补丁,删除make install阶段./run_tic.sh脚本的执行，取消terminfo数据库（可以通过linux x86下编译ncurses-6.5生成，然后推到开发板上）

make -j $(shell nproc) 
make install 

arm 32位的编译也是和64位一样的步骤，笔者不再赘述
