Bug ID: 85326
Summary: `make check` fails with `--disable-bootstrap` and
`--enable-languages=c`
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: edersondisouza at hotmail dot com
Target Milestone: ---
When building gcc from git tree (rev 03d52952b8ed93b676222f957c1a27a24cf3ef71),
`make check` fails if bootstrap is disabled and C is the only language enabled.
Compiled gcc -v output:
~/gcc-build-no-bootstrap$ gcc/xgcc -v
Using built-in specs.
COLLECT_GCC=gcc/xgcc
Target: x86_64-pc-linux-gnu
Configured with: ../gcc/configure --enable-languages=c --disable-bootstrap

libdir=/opt/gcc/lib --prefix=/opt/gcc --libexecdir=/opt/gcc/libexec
Thread model: posix
gcc version 8.0.1 20180409 (experimental) (GCC)
A bit more that one hundred tests fail, all with same message:
C++ compiler not installed on this system.

It appears that some tests, even depending on C++, are run and end up failing.
Note that when using bootstrap, tests execute fine [one unrelated test fail on
both], apparently due to the fact that gcc still build the C++ compiler despite
the `--enable-languages=c` flag.
If there's anything else I can provide to help, please let me know.
