Subject: [PATCH] llvm: Do not use find_library for ncurses

This ensures that it lets OE to decide which lib to link
otherwise it adds absolute paths to linker cmdline and confuses it
horribly with native and target libs when build clang for target

TOPDIR/build/tmp/work/cortexa57-yoe-linux-musl/clang/12.0.0-r0/recipe-sysroot-native/usr/lib/libtinfo.so: error adding symbols: file in wrong format
clang-12: error: linker command failed with exit code 1 (use -v to see invocation)

Upstream-Status: Pending
