Commit Message

Nathan Sidwell Feb. 18, 2021, 8:39 p.m. UTC 
PR99023's testcase is highlighting some missing functionality of the 
modules test harness.  I did have some partial support, but it's only 
use in one place for a now-obsolete test.  This patch expunges that 
support so I can add better functionality now I understand better what 
is necessary.

         * modules.exp: Remove dg-module-headers support
         * alias-2_a.H: Delete.
         * sys/alias-2_a.H: Delete.
