[Qemu-devel] [PATCH qemu] configure: Enable werror for git worktrees

[Alexey Kardashevskiy]

The configure script checks multiple times whether it works in a git
repository and it does this by "test -e "${source_path}/.git" in 4 cases
but in one case where it tries to enable werror "-d" is used there which
fails on git worktrees as .git is a file then and not a directory.

This changes the test to "-e" as other occurrences.
