Hello libtool devs,
There's a common information/warning message that occurs with building secp256k1 for example where it states:
"/usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')"
This can be resolved if "cru" is changed to "crU" in:
/usr/share/aclocal/libtool.m4
Please consider doing this, thank you !
