Avoid using the x86-specific implementations on non-sse2 x86 Upstream has said that the x86-specific implementation requires sse2, and now enforces this via a static assert.
This patch replaces all checks in "src" for x86 with checks for x86 with sse2 and also inhibits the build of assembler on x86 without sse2. This should cause the generic implementations to be used.
The changes to "src" were created with the command for file in `find src -name '*.rs'` ; do sed -i 's/target_arch = "x86"/all(target_arch = "x86", target_feature = "sse2")/g' $file ; done
