How would I verify/debug this for sure? I haven't been setting
anything differently when I build under Steam-Runtime vs. Ubuntu. (And
I have gotten through a pure Linux (no Android) build under
Steam-Runtime successfully.) Steam-Runtime is just a Linux. (It is
originally derived from Ubuntu 12.04LTS, though it probably has all
its Ubuntu identifiers stripped/replaced.)


I checked the CMakeCache.txt in build/Ninja-ReleaseAssert/swift-linux-x86_64

Both files are identical between the Steam-Runtime and Ubuntu versions
when building for Android. The variable SWIFT_SDKS is:
SWIFT_SDKS:STRING=ANDROID;LINUX


Obviously something is different somewhere since it seems to be
skipping the glibc.modulemap in the Steam-Runtime case.


Thanks,
