[PATCH 15/17] argp-standalone: Add recipe

[Khem Raj <raj.khem@gmail.com>]

This helps packages like gnutls to compile with musl
any package that needs glibc's implementation of argp
can link to this library

+Subject: restrict value range passed to isprint function
+
+According to C standards isprint argument shall be representable as an
+unsigned char or be equal to EOF, otherwise the behaviour is undefined.
+
+Passing arbitrary ints leads to segfault in nm program from elfutils.
+
+Restrict isprint argument range to values representable by unsigned char.
