[PATCH] ld: Unify the directory separator on Windows.

This patch is a spin-off of the following discussion:
https://inbox.sourceware.org/binutils/[email protected]/

When the linker searches for a file, it constructs the full file name by
concatenating the search path, the directory separator, and the file name.
As a result, on Windows users may encounter paths like this:

[...]
attempt to open D:/Works/binutils/ld/testsuite/ld-archive\tmpdir/a.o failed
[...]

or even like this:

[...]
D:\Works\xcomp\build-binutils-h8300-mingw\ld\ld-new.exe: cannot open linker script file D:/Works/binutils/ld/testsuite/ld-scripts\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\././././.\./././././/libpr33265-2.a: No such file or directory
[...]

This is a safe change, as the linker has been using forward slashes on
Windows for a long time, and this piece of code appears to be a leftover
from the dark Windows 9x era.
