rpmbuild rust-toolset-1.29-rust-1.27.1-1.el7 output in rhel-alt-7.5 aarch64

Description of problem:
There are few testcases regressions found in rust-toolset-1.29-rust-1.27.1-1.el7 in comparison to previous rust-toolset-7-rust-1.26.2-3.el7 in rhel-alt-7.5 aarch64:

test [compile-fail] compile-fail/huge-array.rs ... FAILED
test [debuginfo-gdb] debuginfo/by-value-self-argument-in-trait-impl.rs ... FAILED

It might be worth mentioning that rust-toolset-1.29-rust-1.27.1-1.el7 was build with RUST_BACKTRACE=0 due to bug #1611006, while rust-toolset-7-rust-1.26.2-3.el7 used for this comparison was tested with backtrace enabled (RUST_BACKTRACE=1).

Also, these 2 failures were not found in other arches.

Version-Release number of selected component (if applicable):
rust-toolset-1.29-rust-1.27.1-1.el7

Steps to Reproduce:
1. rpmbuild --rebuild ./rust-toolset-1.29-rust-1.27.1-1.el7.src.rpm

Output of the failures:
