The recent suffix-log-path_test.c checks for a full stacktrace and
since on some arm-linux-gnu configuration the slow unwinder is used
on default (when the compiler emits thumb code as default), it
requires -funwind-tables on tests.
It also seems to fix the issues disable by d025df3c1d.

The tests do not report the expected leak when issued with use_stack
or use_tls option equal to 0 on arm-linux-gnueabihf (ubuntu 18.04,
glibc 2.27).

Summary:
Newer libstdc++ has global pool, which is filled with objects
allocated during libstdc++ initialization, and never released.
Using use_globals=0 in the lit tests results in these objects
being treated as leaks.
Fix this by porting several tests to plain C, and introducing
a simple sanity test case for __lsan::ScopedDisabler.
