Confirmed: this is trivial to reproduce by running:
make check-jit
to build the test programs, or just one like so:
make check-jit RUNTESTFLAGS="-v -v -v jit.exp=tut01-hello-world.c"
then running:
./testsuite/jit/tut01-hello-world.exe
outside of the jit.exp harness (thus not setting up the envvars).

Segfault occurs if driver is not found on PATH *and* the context's
GCC_JIT_STR_OPTION_PROGNAME is NULL.

...and hence only the tutorials run into this; the rest of the testsuite uses
harness.h, which sets that option to non-NULL.

Note: with the fix, the testcase (with an unset PATH) emits these error
messages for me:
libgccjit.so: error trying to exec 'x86_64-unknown-linux-gnu-gcc-5.0.0':
execvp: No such file or directory
libgccjit.so: error: error invoking gcc driver: exit_status: 65280 err: 0
libgccjit.so: error: whilst attempting to run a driver named:
x86_64-unknown-linux-gnu-gcc-5.0.0
libgccjit.so: error: PATH was: (null)
which hopefully should make it clearer that it's a PATH issue.
