Subject: [PATCH] Fix final link of notmuch binary to use C compiler if
 possible.

On Linux, a C program that depends on a C library which in turn
depends on a C++ can be linked with the C compiler, (avoiding a direct
link from the program to the C++ runtime libraries).

Other platforms with less fancy linkers need to use the C++ compiler
for this linking.
