Error:Syntax error: redirection unexpected

在安装Android NKD后执行make-standalone-toolchain.sh时出现错误“make-standalone-toolchain.sh: 701: ./make-standalone-toolchain.sh: Syntax error: redirection unexpected”，同时执行时出现警告“WARNING: The shell running this script isn't bash. Although we try to avoid bashism in scripts, things can happen.”

打开脚本701行

for ABI in $(tr ',' ' ' <<< $ABIS); do

经查，应为"<<<"的问题。在执行时解释器指定为bash，则无错误。
