rust: Fix build failure for v1.83 when lib32 enabled
Because of the following commit ,
https://github.com/rust-lang/rust/commit/68034f837a39387e49fc7d7c5b088f5372a1127e
when we enable lib32, getting build failure because there is a check for target
support for "-Zdual-proc-macros" flag not functioning properly when lib32 is
enabled in the build environment. So for now reverting this commit and bring
back the previous behavior, where the "-Zdual-proc-macros" flag is always
added for building proc macros, regardless of the target architecture's support.
This would bypass the check introduced in the patch, allowing the build to
proceed without error, even when building for a 64-bit architecture with lib32 enabled.
