    _______________________________________________________

Details:

ctype.S contains several separately compiled functions that branch to
__cty_isfalse and __cty_istrue. The compiled functions end up in the same
linker section but if several functions are compiled and linked together the
section gets too large and the __cty_isfalse branch is too far for BRNE,
BRGE, etc instructions (+/- 64 words).
In that case linker complains with a relocation truncated error.

The attached patch change all branches with RJMP calls, that have a range
greater than the whole ctype.S code (+/- 2 Kwords).
