non-GNU libc newlib (also IBM, QNX, and others) define extern function utoa
(also itao, ltoa, ftoa, ultoa, possibly lltoa, ulltoa) in stdlib.h (or
unistd.h) which conflicts with src/libs/libxutil/XFontName.c definition of
utoa as static and causes build failure requiring a patch (attached):
.../src/libs/libxutil/XFontName.c: At top level:

‘utoa’ follows non-static declaration

groff utoa renamed to utoan as groff definition is static with 3rd argument
int buffer size, instead of common unistd.h or stdlib.h declarations with 3rd
argument int conversion radix 2-36 (like inverse of strtod/l family of
functions).
