Building the musl C library on Thumb (Thumb1, not Thumb2), fails with:
{standard input}:20: Error: only lo regs allowed with immediate -- `mov fp,#0'
{standard input}:21: Error: only lo regs allowed with immediate -- `mov lr,#0'
{standard input}:25: Error: unshifted register required -- `and ip,a1,#-16'
Since there are no cores that we support that are Thumb1 only, use the
same solution as the one used by glibc: build the C library in ARM
mode.
