[Samba] talloc configure error for armv8be

[Zheng, Ruoqin]

Hi 
    I have problem when doing configure for talloc-2.1.1. The error message like follows:

  ./configure --prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --libexecdir=/usr/lib64/talloc --datadir=/usr/share --sysconfdir=/etc --sharedstatedir=/com --localstatedir=/var --libdir=/usr/lib64 --includedir=/usr/include --oldincludedir=/usr/include --infodir=/usr/share/info --mandir=/usr/share/man --disable-rpath --disable-rpath-install --bundled-libraries=NONE --builtin-libraries=replace --disable-silent-rules --with-libiconv=…/tmp/sysroots/usr --cross-compile --cross-execute="${CROSS_EXEC}"

This error is caused by using armv8be toolchain，le(little endian) is ok. 
I think there is something wrong with uname sysname.
Does anyone know the reason?
