        src/lib/libc/arch/arm/sys: cerror.S

Log Message:
arm: cerror.S - factor out code to return -1

Do not repeat verbose ifdefed code that sets (long long){ r0, r1 } to
-1LL that indicates an error return from a syscall.  Define it once as
a macro and use it.  Fix the code to actually be compilable as thumb
("mov" vs "movs").

Modulo one fixed "mov" vs "movs" the same object code is generated for
all 8 permutations of (arm/thumb x non/reentrant x absolute/pic).
