-Subject: [PATCH] gcc/Makefile.in: move SELFTEST_DEPS before including language
- makefile fragments
-
-As reported by several Buildroot users [1][2][3], the gcc build
-may fail while running selftests makefile target.
-
-The problem only occurs when ccache is used with gcc 9 and 10,
-probably due to a race condition.
-
-While debuging with "make -p" we can notice that s-selftest-c target
-contain only "cc1" as dependency instead of cc1 and SELFTEST_DEPS [4].
-
-  s-selftest-c: cc1
-
-While the build is failing, the s-selftest-c dependencies recipe is
-still running and reported as a bug by make.
-
-  "Dependencies recipe running (THIS IS A BUG)."
-
-A change [5] in gcc 9 seems to introduce the problem since we can't
-reproduce this problem with gcc 8.
-
-As suggested by Yann E. MORIN [6], move SELFTEST_DEPS before
-including language makefile fragments.
-
-With the fix applied, the s-seltest-c dependency contains
-SELFTEST_DEPS value.
