Summary:                    [PORTABILITY] GNU libc asprintf dependency
Description: 
libbb/bb_asprintf.c fails to compile without GNU vasprintf. A simple
fallback is to first call snprintf with NULL string argument to get the
length (excluding terminator byte), malloc, then call snprintf again with
the new buffer.

Its require the auto configure infrastructure. 
I don`t know, how detect supporting asprintf in libbb internally in the
compiling process.

I've found other dependencies on GNU functions too, like strndup (that one
is stupid though since it obviously should be replaced by bb_xstrdup). IMO
one possible solution is to have a manual configuration option to disable
dependence on all GNU-specific functions and use portable replacements for
them (at a possible but minor size/performance penalty).
