For which architecture do you (cross) compile (what is your target architecture)?

According to e.g. [1]:

[...]
  7 CAN_BUILD_X86_64 := $(shell ../x86/check_cc.sh $(CC) \
  8   
[...]
 19 TEST_CUSTOM_PROGS := $(OUTPUT)/test_sgx
 20 
 21 ifeq ($(CAN_BUILD_X86_64), 1)
 22 all: $(TEST_CUSTOM_PROGS) $(OUTPUT)/test_encl.elf
 23 endif
[...]

test_sgx is only compiled for x86_64 (and/or CAN_BUILD_X86_64 is true)...

Regards,
Peter
