Fix SDL2 frontend build failure for linux relating to linker option order in Makefile

[fcard]

The order in which the link options are placed in relation to the input files matter for certain linkers (gnu ld, for example)

GCC docs: https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html Relevant excerpt:

-llibrary -l library [...] It makes a difference where in the command you write this option; the linker searches and processes libraries and object files in the order they are specified. Thus, ‘foo.o -lz bar.o’ searches library ‘z’ after file foo.o but before bar.o. If bar.o refers to functions in ‘z’, those functions may not be loaded.
