Long ago (#40549) we enabled the `uwtable` attribute on Windows by default (even with `-C panic=abort`) to allow unwinding binaries for [stack unwinding information][winstack]. It looks like this same issue is [plaguing][arm1] Gecko's Android platforms [as well][arm2]. This commit applies the same fix as #40549 except that this time it's applied for all Android targets. Generating a `-C panic=abort` binary for `armv7-linux-androideabi` before this commit generated a number of `cantunwind` functions (detected with `readelf -u`) but after this commit they all list appropriate unwind information. Closes #49867 [winstack]: https://bugzilla.mozilla.org/show_bug.cgi?id=1302078 [arm1]: https://bugzilla.mozilla.org/show_bug.cgi?id=1453220 [arm2]: https://bugzilla.mozilla.org/show_bug.cgi?id=1451741
