Workaround: link with -Wl,--allow-multiple-definition (thanks to Adrian
Bunk).
I think we're more likely to replace mozjs91 in gjs' dependencies with
mozjs102 and remove mozjs91 than we are to fix mozjs91, but I'm mentioning
this here in case it becomes necessary to use mozjs91 for some reason.
Linking with -Wl,--allow-multiple-definition seems like a less bad
workaround than using a non-default gcc.
