            Bug ID: 35504
           Summary: r319264 causes '-Wl,' to be replaced with '-Wl;'
           Product: Build scripts
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: cmake
          Assignee: unassignedbugs at nondot.org
          Reporter: ahmed.bougacha at gmail.com
                CC: llvm-bugs at lists.llvm.org

After r319264, thinlto bootstraps fail to build with:

FAILED: : &&
CMakeFiles/cmTC_dd6fc.dir/testCCompiler.c.o -o cmTC_dd6fc && :
Undefined symbols for architecture x86_64:
"_main", referenced from:
implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
/bin/sh: -cache_path_lto: command not found
/bin/sh: THINLTO_CACHE: is a directory
ninja: build stopped: subcommand failed.

because we now replace '-Wl,' in BOOTSTRAP_ variables with '-Wl;'.
