[swift-lldb-dev] [swift-dev] repl/test-repl-glibc.py Failure on Ubuntu

[Ryan Lovelett]

I've played around with `git bisect` and I think I've tracked it down to
this commit [1]. Which came from PR #1704 [2]. I've also updated the
issue, SR-1109, to include this information.
 
c6121d56b19305cf59148d46af54c06b771f3180 is the first bad commit

[Un-revert][Glibc] Configure modulemap for target, not host
    
This reverts commit f2154ee94d, which reverted 04e1cd5bda. The original
commit needed to be reverted because of an issue in which install
targets were added to OS X builds that did not target Linux. This
addresses that issue by guarding all the Linux-only CMake logic with a
check for the SDK being built.
