Issue Description:

This issue was discussed in https://forums.swift.org/t/linker-error-on-ubuntu-18-04-swift-5-1-2/31168.

When building a "large" Swift project on Linux such as https://github.com/finlabsuk/open-banking-connector it seems the following error is produced on linking:

swift build /usr/bin/ld.gold: fatal error: out of file descriptors and couldn't close any clang-7: error: linker command failed with exit code 1 (use -v to see invocation) :0: error: link command failed with exit code 1 (use -v to see invocation) [0/1] Linking ProjectName

The issue is reproducible with the above-mentioned project on Swift 5.1.2 / Ubuntu 18.04 (build instructions here: https://github.com/finlabsuk/open-banking-connector/blob/master/docs/installation-and-use.md).

Analysis (https://forums.swift.org/t/linker-error-on-ubuntu-18-04-swift-5-1-2/31168/8) suggests the cause is related to the compiler producing a high number of output files per input files which might be reducible. In any case an actionable error message would be helpful as this situation seems to arise quite easily.

@aciidb0mb3r Is it SwiftPM that decides to link all of these together in a single job?

This could also be made worse by https://bugs.swift.org/browse/SR-12292

Is there a workaround for this? Also experiencing this with Swift 5.5.3 on Al2
