Not using $(UDEFS) in makefile rule: `$(OBJDIR)/pdex.${DYLIB_EXT}: OBJDIR`

running Linux.

in the file: PlaydateSDK-1.12.0/C_API/buildsupport/common.mk

line 154, i believe we should add $(UDEFS) to -DTARGET_SIMULATOR=1 -DTARGET_EXTENSION=1.

it'd be nice to include user definitions in this build rule.
