Hmm I don't see that in the x86 version of Ubuntu GCC:

Configured with: ../src/configure -v --with-pkgversion=3D'Ubuntu

Running your command prints nothing:

/path/to/gcc# ./usr/bin/gcc-7 -print-sysroot=20=20=20=20=20=20
/path/to/gcc#

Same with:

/path/to/gcc# ./usr/bin/gcc-7 -no-canonical-prefixes -print-sysroot=20=20=
=20=20=20=20
/path/to/gcc#=
