libgccjit.so is installed by jit/Make-lang.in's jit.install-common,
into $(DESTDIR)/$(libdir).
jit/config-lang.in listed "compilers" as "libgccjit.so", leading
to the makefile variable COMPILERS containing libgccjit.so. This in
turn led to gcc/Makefile's install-common installing a redundant
copy of the library into $(DESTDIR)$(libexecsubdir).
Drop the entry from jit/config-lang.in, eliminating the duplicate copy
of the library.
Tested with a clean rebuild; "make check-jit" and "make install"
continue to work.
Committed to trunk as r220133.
