It seems that clang is being picked up as the main compiler in certain 
situations, ala

ccache gcc -Wall -Wmissing-prototypes -Wpointer-arith 
-Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute 
-Wformat-security -fno-strict-aliasing -fwrapv 
-fexcess-precision=standard -g -O0 -fno-omit-frame-pointer 
-I../../../src/include  -D_GNU_SOURCE -I/usr/include/libxml2   -c -o 
auth-scram.o auth-scram.c -MMD -MP -MF .deps/auth-scram.Po
ccache gcc -Wall -Wmissing-prototypes -Wpointer-arith 
-Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute 
-Wformat-security -fno-strict-aliasing -fwrapv 
-fexcess-precision=standard -g -O0 -fno-omit-frame-pointer 
-I../../../src/include  -D_GNU_SOURCE -I/usr/include/libxml2   -c -o 
be-secure-openssl.o be-secure-openssl.c -MMD -MP -MF 
.deps/be-secure-openssl.Po
/usr/lib64/ccache/clang -Wno-ignored-attributes -fno-strict-aliasing 
-fwrapv -O2  -I../../../src/include  -D_GNU_SOURCE 
-I/usr/include/libxml2  -flto=thin -emit-llvm -c -o be-fsstubs.bc 
be-fsstubs.c
/usr/lib64/ccache/clang -Wno-ignored-attributes -fno-strict-aliasing 
-fwrapv -O2  -I../../../src/include  -D_GNU_SOURCE 
-I/usr/include/libxml2  -flto=thin -emit-llvm -c -o namespace.bc namespace.c

I would expect LLVM to be isolated to the jit/ hierarchy.

Using CC="ccache gcc" and --with-llvm.

And congrats on getting the feature in !
