Hi,

I encounter an issue while working with glibc with script scripts/mkinstalldirs. In scriptversion=2018-03-07.03; # UTC.

I had a symbolic link lib64->lib and the folder lib did not exist.

The glibc installing process is calling   ./scripts/mkinstalldirs [..]/lib64 which failed to mkdir -p it.

I made a working patch for my case, which need to be reworked as a loop (As I use the script with a single argument $@ and not a list of them).

Here is my solution:
