YongQin, You probably can use the option "showcommands" to see there is any difference during the compile/strip process.I compared the output, there is no big difference except the following 2 header files paths specified for flo platfomr:
-isystem device/asus/flo/kernel-headers -isystem hardware/qcom/msm8960/kernel-headersI don't think these options make the difference.
nexus9.txt is the output for flounder platform. nexus7.txt is the output for the flo platform.
Thanks, Yongqin Liu

My 2 cents: Is it possible that you dump the build command of libc.so for flo and flounder? For your build log, flo is 32bit android while flounder is 64bit. 32bit libc 64bit android is built as 2nd arch. It may be something different there.
