[PATCH][next] gcc-plugins: randstruct: Update code comment in relayout_struct()

From: Gustavo A. R. Silva
Date: Sat Nov 25 2023 - 16:55:27 EST


Update code comment to clarify that the only element whose layout is
not randomized is a proper C99 flexible-array member. This update is
complementary to commit 1ee60356c2dc ("gcc-plugins: randstruct: Only
warn about true flexible arrays")
