I meant to say that configure --help also does not show this option.

The glibc version is glibc-2.12.90-17.x86_64.

As Jonathan Wakely pointed out on the gcc-help list, the glibc is most likely
too old.

I'd suggest that configure warns about that and disables libsanitizer. Also,
the configure.html in INSTALL should mention this option. configure --help does

(This is not a duplicate of 61021 or 61955 as the breakage point is a different
one. However, the solution might fix all instances of this.)

            Bug ID: 61996
           Summary: [SH] -musermode conflicts with
                    -matomic-model=soft-imask
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: olegendo at gcc dot gnu.org
            Target: sh*-*-*

Originally reported log:

checking for suffix of object files... configure: error: in
`/data/fedora/cross-gcc/gcc-4.9.1-20140717/sh-linux-gnu/sh-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

[in config.log]
conftest.c:1:0: error: cannot use atomic model soft-imask in user mode

It seems that when building for SH1/SH2/SH2A sh-linux, the -musermode option is
set by default and then conflicts with the default -matomic-model=soft-imask
setting.

Proposed fix:
- musermode should have no effect on SH targets that don't have user/privileged
modes (SH1, SH2, SH2A).

- mno-usermode should be added to allow disabling user mode restrictions when
it is enabled by default (i.e. in sh-*-linux case).

--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
2.6.32 (the last LTS for 2.6.x release) support was finished in 2016.
So just closing as won't fix.  5 years after the newest kernel release of that
release series is long enough.
