[PATCH 0/1] MR7371: makefiles: Handle absolute path in create_dir() due to --with-wine64=(absolute path).

[Jinoh Kang (＠iamahuman)]

Since commit 7620f21ff98 (makefiles: Generate the wow64 symlinks from
makedep., 2025-02-18), makedep generates a symlink target for
"<wine64_dir>/loader-wow64".  This causes <wine64-dir> to be added as an
"ignore path," ultimately leading to create_file_directories() and then
create_dir().

create_dir() only expects relative paths.  If it's passed an absolute
path, it will recognize the "/" prefix as an empty path component
followed by slash, and will attempt to mkdir(""), which fails.

Fix this by skipping initial slashes in create_dir().

Fixes: 7620f21ff98a85249b0b110bcba9953b32763f28
