The underlying reason is mentioned in the commit message referenced by the URL of this bug: mmx support has been removed in recent rust, while third_party packed_simd in thunderbird still contains those pieces. 3:49.36 error[E0432]: unresolved import `crate::arch::x86_64::__m64` 3:49.36 --> /var/tmp/portage/mail-client/thunderbird-78.5.0/work/thunderbird-78.5.0/third_party/rust/packed_simd/src/api/into_bits/arch_specific.rs:51:15 3:49.36 | 3:49.36 51 | $($arch_ty),* 3:49.36 | ^^^^^^^^ no `__m64` in `arch::x86_64` 3:49.36 ... 3:49.36 86 | / impl_arch!( 3:49.36 87 | | [x86["x86"]: __m64], [x86_64["x86_64"]: __m64], 3:49.36 88 | | [arm["arm"]: int8x8_t, uint8x8_t, poly8x8_t, int16x4_t, uint16x4_t, 3:49.36 89 | | poly16x4_t, int32x2_t, uint32x2_t, float32x2_t, int64x1_t, 3:49.36 ... | 3:49.36 96 | | test: test_v64 3:49.36 97 | | );

Created attachment 674833 [details, diff] 05-mmx-removed-from-rust-cranes-packed_simd-checksum-failure.patch Cargo punishes you upon making changes to the sources. Let's upgrade the checksums to calm down cargo. Welcome to the world of rust.
Thanks for the patches but should be already fixed, see bug #756334 (which applied fixes for thunderbird, firefox, and spidermonkey). I don't see your emerge --info to confirm but likely missing the fix, so please emerge --sync and try again.

Thanks for the heads up. Had I found that bug, I wouldn't have spent time on this...
