In 0.9.36, there was a missing symbol that caused
```
libskiko-linux-x64.so: undefined symbol: _ZNSt19_Sp_make_shared_tag5_S_eqERKSt9type_info
```

It's because the build attempts to statically link the C++ standard
library, but:
- Skia's object files reference newer libstdc++ symbols
- GCC 7.3's `libstdc++` doesn't contain these symbols
- The static linking fails to resolve these symbols

GCC was downgraded from 9 to 7 in #1130 during the switch to AL2 to
provide better GLIBC compatibility.
Since AL2
[provides](https://docs.aws.amazon.com/linux/al2/ug/c-cplusplus.html)
only GCC 7.3 by default and GCC 10, installing GCC 9 is problematic
there, so it's bumped to 10

However, GCC 10 introduces outline atomics as default for new ARM chips,
the build might fail due to missing symbols like
```
org_jetbrains_skia_FontMgrWithFallback__1nDefaultWithFallbackFontProvider: error: undefined reference to '__aarch64_ldadd4_relax'
org_jetbrains_skia_FontMgrWithFallback__1nDefaultWithFallbackFontProvider: error: undefined reference to '__aarch64_ldadd4_acq_rel'
```
so, to keep things compatible with the previous GCC version,
`-mno-outline-atomics` option was added to disable this new behavior.
