Mac OS 11.2.1 “Big Sur”: Removing whitespace segfaults

[halian]

When attempting to build any branch, gfx throws the following error when attempting to remove whitespace from battle animations:

gbgfx  -o gfx/battle_anims/hit.2bpp gfx/battle_anims/hit.png
tools/gfx --remove-whitespace -o gfx/battle_anims/hit.2bpp gfx/battle_anims/hit.2bpp
make: *** [gfx/battle_anims/hit.2bpp] Segmentation fault: 11
make: *** Deleting file `gfx/battle_anims/hit.2bpp'

I assume this is an upstream issue and will probably be fixed at some point in the upstream toolchain. I'll leave this open until I can update the reference version of pokecrystal.
