Subject: Fix incremental build on Unix (dotnet/coreclr#9779)
X-Git-Tag: submit/tizen/20210909.063632~11030^2~7892
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=242918faa45d40d1fe24cf5c508310675f808b23;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Fix incremental build on Unix (dotnet/coreclr#9779)

This change fixes issue with dactablerva.h being generated even if the
libcoreclr.so hasn't changed. Also, the dependency of the daccess.cpp
on this header was not honored by the build system and so even if the
dactablerva.h was regenerated with a different contents, the daccess.cpp
was not rebuilt.

Commit migrated from https://github.com/dotnet/coreclr/commit/6af7b26738149d46eaccbce631d670c949527ada
