Makefile.global has this reference to ccache on RHEL 9 and Fedora:

CLANG = /usr/lib64/ccache/clang

which is caused by:

%if 0%{?rhel} && 0%{?rhel} == 8
        export CLANG=%{_bindir}/clang LLVM_CONFIG=%{_bindir}/llvm-config-64
%endif

(so this issue does not exist on RHEL 8).

Pushed a fix to PostgreSQL 17. I'll check the results tomorrow, and then
will patch PostgreSQL 11+.

Greg: Thanks for the report. The changes will appear in next month's
minor release set (Nov 9). I'm not inclined to push an update set just
for this issue.
