from this answer #5 (comment):

Add -fcommon to COPTS: Append the -fcommon flag to the existing flags in the COPTS variable.

COPTS = -funroll-loops -O3 -ansi -std=c99 -pedantic-errors -Wall -I$(CFITSIOINCDIR) -D_GNU_SOURCE -fcommon
Adding -fcommon will instruct the compiler to place uninitialized global variables in a common block, which can be shared between different compiled source files. This approach can solve the multiple definition linker errors but may result in slightly less efficient code. This change is recommended if the codebase relies on older C standards or practices where multiple definitions are expected.

This worked for me :)
