Commit Message
This reverts commit 7bba0ad08576309763e3f41193eaa93025e10b8b.
Tom de Vries reported that 7bba0ad0857 (gdb/compile: Use
std::filesystem::remove_all in cleanup) broke builds with gcc-7.5.0
which mostly supports c++17, but not std::filesystem[1]. As this change
is not critical, revert it to maintain compatibility.

Thanks. Could you put the 'Bug:' tag into this so it's recorded in
bugzilla?
Sorry to say it but this is ok. I appreciate your quick turnaround on
it.

I have added the Bug tag and pushed to master. This should fix the
issues for builders with older toolchains.
Thanks,
Lancelot.
