[PATCH] src/libs/libxutil/XFontName.c(utoa): non-GNU stdlib.h conflict

[Brian Inglis]

gcc 11.3 build failure when static utoa definition in XFontName.c
conflicts with extern utoa declared in stdlib.h
third argument is usually int conversion radix instead of groff int
buffer size in non-GNU libc including newlib, QNX, IBM, others

make[1]: *** [Makefile:8017: src/libs/libxutil/libxutil_a-XFontName.o] Error 1

utoa renamed to utoan as groff definition is static with 3rd argument
int buffer size instead of conversion radix

[other functions commonly defined are itoa, ultoa, ftoa, dtoa]
