strip: Unable to recognise the format of the input file

Sometimes U got error while doing 'make install' :
strip: Unable to recognise the format of the input file

This is because the flag "INSTALLSTRIP = -s" in file config.mak
will pass to 'install' application while you do "make install" ..........
disable the flag "INSTALLSTRIP = " and make install.;0)

Or edit flag "INSTALL = $your_arm_install_application"

PS;===============================================
一般发生在交叉编译的时候。
因为安装时的install程序检测到标志INSTALLSTRIP = -s ----即需要
执行 strip 来剔除一些无用的符号。而此时 strip 又只是宿主机的，所以
不能 strip 目标机的文件。
