dkpsp: Incorrect COMPILER_PATH

[173210]

c:/devkitpro/devkitpsp/bin/../libexec/gcc/psp/4.6.2/ is duplicated, and c:/devkitpro/devkitpsp/bin is not includes, thus collect2 can't find tools.
It disables to build https://github.com/173210/valentine-hbl.git, which invokes ld via GCC to use lto plugin.
The bug is confirmed on Windows, but not on Ubuntu.

COMPILER_PATH=c:/devkitpro/devkitpsp/lib/gcc/../../libexec/gcc/psp/4.6.2/;c:/devkitpro/devkitpsp/lib/gcc/../../libexec/gcc/;c:/devkitpro/devkitpsp/bin/../libexec/gcc/psp/4.6.2/;c:/devkitpro/devkitpsp/bin/../libexec/gcc/psp/4.6.2/;c:/devkitpro/devkitpsp/bin/../libexec/gcc/;c:/devkitpro/devkitpsp/bin/../lib/gcc/psp/4.6.2/../../../../psp/bin/;c:/devkitpro/devkitpsp/bin/../lib/gcc/psp/4.6.2/../../../../psp/bin/

But you have no removed it from the repository yet. Can I make a pull request to fix this bug and update toolchains?
