Use stat, instead of strcmp, to check if the same linker script file
appears multiple times for
$ ld -L... -T ././/script.t -T script.t ...
Although ././/script.t and script.t access the same file, but their
filenames are different. strcmp won't work here.
Copy gnulib/import/same-inode.h to include since the gnulib directory
isn't included in the binutils tarball.

(ldfile_find_command_file): Change the second argument from bool
to enum script_open_style. Check if the same linker script file
appears multiple times by using stat, instead using strcmp.
(ldfile_open_command_file_1): Don't check if the same linker
script file appears multiple times here.
