Arch Linux w/ devkitPPC r44.2-2: Unrecognized command-line option when building tools (Wii U target)

[halian]

Describe the bug
Building the tools with make tools fails due to an unrecognized command-line option.

To Reproduce
Steps to reproduce the behavior:

1. Clone repository
2. Add baserom with the proper filename
3. make tools
4. Watch the output

Expected behavior
The tools compile without incident, that I may compile the game proper for my Wii U.

Can you change -pthread to -lpthread in tools/Makefile (line 49)?

[halian]

I changed -pthread to -lpthread on line 47 of tools/Makefile and it now fails with:

/opt/devkitpro/devkitPPC/bin/../lib/gcc/powerpc-eabi/13.2.0/../../../../powerpc-eabi/bin/ld: cannot find -lpthread: No such file or directory
