REL_TYPE undeclared on non-x86_64 architectures (aarch64)

[SamHerts]

Building Spindle TestSuite on non-x86_64 architectures (aarch64) fails with a compile error

testsuite/symbind_test.c:139:2: error: #error Need rel type for architecture
139 | #error Need rel type for architecture
    |  ^~~~~

Root cause:

REL_TYPE is defined in the architecture guard block but not for other architectures:

Spindle/testsuite/symbind_test.c

Lines 136 to 138 in e731f24

	#if defined(__x86_64)
	#define REL_TYPE ElfW(Rela)
	#else

Suggested fix

Add the appropriate architecture type constant for other architectures in the guard block.

#if defined(__x86_64) || || defined(__aarch64__)
#define REL_TYPE ElfW(Rela)
#else
#error Need rel type for architecture
#endif

Environment

• Spindle: devel branch (commit 4174224)
• OS: Rocky Linux 10.1 (Red Quartz)
• Compiler: GCC 15 (gnu15 toolchain)
• Affected file: testsuite/symbind_test.c
