+Subject: [PATCH] sys_defs.h: workaround for musl lib
+
+Fix musl lib compile failure:
+vbuf_print.c:215:46: error: macro 'VBUF_SNPRINTF' passed 5 arguments, but takes just 4
+  215 |                     VSTRING_ADDNUM(fmt, width);
+      |                                              ^
+vbuf_print.c:132:9: note: macro 'VBUF_SNPRINTF' defined here
+  132 | #define VBUF_SNPRINTF(bp, sz, fmt, arg) do { \
+
+Previously checking condition will make #else branch is selected, and
+NO_SNPRINTF is defined, and when NO_SNPRINTF is defined, VBUF_SNPRINTF
+only take 4 arguments, and cause above failure. musl lib support
+snprintf and we only have glibc and musl libc, so workaround by when
+glibc is not defected, take it as musl lib, and select the #if branch.
