General notes:

I try to build Qubes OS with the latest kernel version available as defined in https://www.qubes-os.org/doc/qubes-builder/, the build environment is fedora 26, the sources are the last available on the qubes-builder respository on the master branch, they match the tag "mm_4e03c122".
After executing "make qubes", I got the error above.

I had a look on the directory ../home/user/rpmbuild/BUILD and within I found a directory named "gcc-6.4.1-20170727.tar.bz2" instead of "gcc-6.4.1-20170727", it could be an error in the extraction command for the archive within the generated rpm-tmp script. As the rpm-tmp file is each time generated with a new name and as the directory BUILD is cleaned after executing "make qubes" , I cannot try to correct this directly.
Any idea how to correct this?

Kind Regards

Indeed looks like a archive handling bug. I'll fix it in a moment. But believe me, you don't want to build gcc yourself, it takes 12h+... You can use pre-built package from yum.qubes-os.org by removing it from COMPONENTS (a list of things to build locally) setting in builder.conf and adding USE_QUBES_REPO_VERSION = 4.0 instead.
