[poky] libtool-cross failed configure on yocto-2.6.1 with newlib

[张忠山]

My host system is:
    
    Linux gfcd101 4.15.0-46-generic #49~16.04.1-Ubuntu SMP Tue Feb 12 17:45:24 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

And using yocto-2.6.1 with newlib:

    TCLIBC := "newlib"

I wrote a custom .bb to build "kconfig-frontends", it "inherit autotools"

when run "bitbake kconfig-frontends", libtool-cross failed to configure:

    ERROR: libtool-cross-2.4.6-r0 do_configure: configure failed

The log file is:
