Bug#883186: e2fsprogs FTBFS on mips64el: undefined reference to `posix_fadvise64'

[Helmut Grohne <helmut@subdivi.de>]

Source: e2fsprogs
Version: 1.43.7-1
Severity: serious
Justification: FTBFS
User: helmutg@debian.org
Usertags: rebootstrap

I was investigating a bootstrap failure for mips64el
(https://jenkins.debian.net/job/rebootstrap_mips64el_gcc7_nobiarch/51)
and wondered whether this was a native issue. Indeed a native build of
e2fsprogs fails on mips64el and the build log ends as follows:

| /usr/bin/make -C /home/helmutg/e2fsprogs-1.43.7/debian/BUILD-STD/e2fsck V=1 e2fsck.static

Since this could either be a mips issue or a glibc issue, I put both
lists into X-Debbugs-Cc and hope that someone will sort this out.
