Subject: aarch64: morello: Use separate lp64 and morello sysdep directories
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4fc40722403a0e88a35764b676819cba3a0e821c;p=thirdparty%2Fglibc.git

aarch64: morello: Use separate lp64 and morello sysdep directories

Provide separate directories for lp64 and purecap abi related sysdep
functionality.

purecap may be better name than morello, but we started with morello
and that is more future compatible with alternative cheri-like
extensions on top of aarch64.
