diffoscope output to corrobate the bug entry

libtool contains two instances of host build references:

1. LTCFLAGS:

LTCFLAGS="·​-​O2·​-​pipe·​-​g·​-​feliminate-​unused-​debug-​types·​-​fdebug-​prefix-​map=/​tmp/​ramdisk/​build-​repro-​no-​dpkg-​2017-​06-​12/​work/​i586-​poky-​linux/​libtool/​2.​4.​6-​r0=/​usr/​src/​debug/​libtool/​2.​4.​6-​r0·​-​fdebug-​prefix-​map=-​native=·​-​fdebug-​prefix-​map==·​-​ffile-​prefix-​map=/​tmp/​ramdisk/​build-​repro-​no-​dpkg-​2017-​06-​12/​work/​i586-​poky-​linux/​libtool/​2.​4.​6-​r0/​libtool-​2.​4.​6=/​libtool-​2.​4.​6/​·​·​-​ffile-​prefix-​map=/​tmp/​ramdisk/​build-​repro-​no-​dpkg-​2017-​06-​12/​work/​i586-​poky-​linux/​libtool/​2.​4.​6-​r0/​libtool-​2.​4.​6=/​libtool-​2.​4.​6/​

2:
lt_truncate_bin="/​tmp/​ramdisk/​build-​repro-​no-​dpkg-​2017-​06-​12/​hosttools/​dd·​bs=4096·​count=1" 

These not only prevent binary reproducibility, but I would assume prevent proper functionality as well.
I believe the remedy would be to set them as:

LTCFLAGS="·​-​O2·​-​pipe·​-​g·​-​feliminate-​unused-​debug-​types
lt_truncate_bin="dd·​bs=4096·​count=1"
