[easybuild] How to get the correct file structure when software and folder have identical names?

[Niek de Klein]

Hi all,

I'm trying to write an .eb file for verifyBamID. The folder where the
executable verifyBamID is located in is also called verifyBamId.

So now when I use

    executables = ['verifyBamID']
    files_to_copy = [(executables, 'bin')]

The path to the executable is
$root/verifyBamID/1.1.2-goolf-1.7.20/bin/verifyBamID/bin/verifyBamID. This
should be $root/verifyBamID/1.1.2-goolf-1.7/20/bin/verifyBamID, both for
clarity and because $root/verifyBamID/1.1.2-goolf-1.7/20/bin/ is added to
PATH.

I have the same problem for other software where the folder name is the
same as the executable. For software where the rest of the .eb file is
exactly the same but where the folder name and executable name are
different it works as expected.

How can I get folder structure to be set correctly when the folder and
software name are the same?

Thanks!
Niek
