[Bug testsuite/45638] New: No rule to make target `check-lto', needed by `check'. Stop.

["zsojka at seznam dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

When gcc is configured with --enable-languages=...,lto,..., make check fails
with:

make[3]: Leaving directory
`/home/smatz/build-164162-lto-fortran-checking-yes-rtl-df/gcc'
make[2]: *** No rule to make target `check-lto', needed by `check'.  Stop.

make[1]: Leaving directory
`/home/smatz/build-164162-lto-fortran-checking-yes-rtl-df'
make: *** [do-check] Error 2

check-gcc, check-g++ and check-gfortran finish fine

I think this never worked (as far as I remember)

According to http://gcc.gnu.org/install/configure.html, --enable-languages=lto
is allowed, as its output by:
gcc $ grep language= */config-lang.in
ada/config-lang.in:language="ada"
cp/config-lang.in:language="c++"
fortran/config-lang.in:language="fortran"
java/config-lang.in:language="java"
lto/config-lang.in:language="lto"
objc/config-lang.in:language="objc"
objcp/config-lang.in:language="obj-c++"
