fix syscall() and __syscall(). r0 has to be set to SYS_syscall or

SYS___syscall, respectively. otherwise sys/arch/sh3/sh3/trap.c will

Create shared ARM source for libc, and move arm26 port over to using it.
...
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.
The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.
