Subject: [PATCH 14/20] localedef: Use initializer for flexible array member
[BZ #24950]
struct charseq used a zero-length array instead of a flexible array
member. This required a strange construct to initialize struct
charseq objects, and GCC 10 warns about that:
cc1: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]

The change makes the object physically const, but it is not expected
to be modified.
