[LLVMdev] buildbot failure in LLVM on clang-x86_64-ubuntu-gdb-75

[Justin Bogner]

This bot seems kind of flaky. In the last 100 builds, it has failed
"gdb-75-check" 22 times with what is either a linker error or a missing
header (or both?):

    gdb compile failed, /usr/bin/ld: error: /home/buildslave/osuosl_slave/clang-x86_64-ubuntu-gdb-75/clang-tests/build/gdb/testsuite/gdb.trace/pendshr1.c.o: requires dynamic R_X86_64_PC32 reloc against 'pendfunc1' which may overflow at runtime; recompile with -fPIC
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    Running ../../../src/gdb/testsuite/gdb.trace/report.exp ...
    Running ../../../src/gdb/testsuite/gdb.trace/save-trace.exp ...
    Running ../../../src/gdb/testsuite/gdb.trace/stap-trace.exp ...
    gdb compile failed, ../../../src/gdb/testsuite/gdb.trace/stap-trace.c:34:10: fatal error: 'sys/sdt.h' file not found
    #include <sys/sdt.h>
             ^
    1 error generated.

Could whoever administers this bot please look into this and either fix
or disable the flaky test?
