- debug asserts in libfbrt will throw an error if the caller tries to detach the main thread
- the test-suite can't recover from this type of failure so must be disabled
- maybe in future if ON ERROR is made to work, we can catch the debug assert

- use RIP-relative addressing to test the address of a procedure in ASM
- error found when testing with latest binutils

With the previous 'mov rax, offset quirk_inline_asm_f1':

Depending on the version of binutils maybe will see this error:
asm.o:fake:(.text+0x4d): relocation truncated to fit: R_X86_64_32S against `.text'

The immediate cause is:
- when the ASM is compiled in to an object file, space is reserved for a 32-bit sign extended address.
- when the object file is linked, the linker is relocating the code to an address that can't be represented by a 32-bit sign extended address.
- therefore we get an error that the address has been truncated

Possible change in binutils:
- binutils 2.34 appears to default the executable image base to 0x40000000
- binutils 2.37 appears to default the executable image base to 0x140000000

…tead of libfb*.a

- build source found in src/fbrt/*.bas, plus OS and taret specific directories
- bulid libfbrt*.a and merge any missing object modules from libfb*.a by coping src/rtlib/obj to src/fbrt/obj

- Change overload to IMAGEINFO( byval as const any ptr, byref as long = 0, byref as long = 0, byref as long = 0, byref as long = 0, byref as any ptr = 0, byref as long = 0 ) as long
