For the regular (system-wide) installation it's OK to assume that Clang is
installed alongside with GCC, probably with the same prefix (usually /usr on
most Linux systems). But this is not so for standalone installations with
custom prefix, where the number of VFS lookups for the suitable GCC
installation may be substantially reduced by filtering out <libdir>/gcc and
(Debian-specific) <libdir>/gcc-cross early, before trying
<libdir>/gcc/<cpu-vendor-os> and <libdir>/gcc-cross/<cpu-vendor-os>,
respectively.
For my installation configured with
-DCMAKE_INSTALL_PREFIX=/home/antipov/.local/llvm-12.0.0, it's possible to
filter out 80 of 200 VFS lookups, from:
