Yes, but the name of the compiler in host/usr/bin now matches the
sysroot directory name, which is what you requested in the first place:

$ ls output/host/usr/
arm-buildroot-linux-uclibcgnueabi  bin  lib  share

$ ls output/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc
output/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc

Note that we are *not* interested in having the sysroot directory name
match the tuple of your original toolchain. What this patch is doing is
that it is making sure that the sysroot directory name matches the
tuple of the Buildroot generated toolchain (which is either a toolchain
fully built by Buildroot, or a set of symlinks+wrapper when an external
toolchain is used).

So the fact that the compiler in output/host/opt/ext-toolchain/ might
have a different tuple is expected.

Best regards,

Thomas
