LOG: [ASan][test] XFAIL global-overflow.cpp etc. on SPARC (#108200)

When enabling ASan testing on SPARC as per PR #107405, two tests `FAIL`
in similar ways as detailed in Issue #108194: at `-O1` and above, one
line of the stacktrace lacks the line number info, causing the tests to
`FAIL`. I could trace this to `clang` generating incomplete line number
info; `g++` gets this right.

To avoid this, this patch `XFAIL`s the affected tests on SPARC.

Tested on `sparcv9-sun-solaris2.11`.
