Build notes⚓︎

• ac_cv_c_undeclared_builtin_options='none needed': the autoconf 2.70+ AC_C_UNDECLARED_BUILTIN test fails on the old GCC 4.6.4 toolchain (it cannot report undeclared builtins even with -fno-builtin), so the cache variable is forced in $(PKG)_CONFIGURE_ENV. Same pattern as flac/glib2/apr-util. This is a GCC-version-specific issue, not uClibc-specific, so a configure-env workaround is used instead of a gate (no regression on any toolchain).
