The test "prefix for system in /" is duplicated in test/prefix.bats.
Both tests are completely identical. This commit removes the
duplication.
It appears that the culprit is this merge from rbenv/master, from 2016:
cf1beda362
With the current development version of bats, this leads to the
following error when running `make test`:
Error:
Duplicate test name(s) in file
"/home/travis/build/pyenv/pyenv/test/prefix.bats":
test_prefix_for_system_in_-2f
Note that the development version is what pyenv's Makefile uses. With
the latest release of bats, the duplication only leads to a warning:
bats warning:
duplicate test name(s) in /src/test/prefix.bats:
test_prefix_for_system_in_-2f
On other systems, we expected to find system Ruby in `/usr/bin`, but in
OpenBSD 5.4 it will be found in `/usr/local/bin`.
This replaces the limited USRBIN_ALT hack with a more generic
`path_without` function that will ensure that the given executable is
not present in the resulting PATH even if it's found in multiple
system paths.
