gnu: Add llvm-15.
* gnu/packages/llvm.scm (llvm-15): New variable.
(llvm-14): Inherit from it, removing duplicated fields.
* gnu/packages/patches/clang-15.0-libc-search-path.patch: New file.
* gnu/local.mk: Register it.

+Clang attempts to guess file names based on the OS and distro (yes!),
+but unfortunately, that doesn't work for us.
+
+This patch makes it easy to insert libc's $libdir so that Clang passes the
+correct absolute file name of crt1.o etc. to 'ld'. It also disables all
+the distro-specific stuff and removes the hard-coded FHS directory names
+to make sure Clang also works on foreign distros.
