[2.26][COMMITTED 3/3] Fix build failure on tilepro due to unsupported atomics

[Siddhesh Poyarekar]

From: Wilco Dijkstra <wdijkstr@arm.com>

        * malloc/malloc.c (malloc_state): Use int for have_fastchunks since
        not all targets support atomics on bool.

(cherry-picked from 2c2245b92ccf6344b324d17d8f94ccd3b8c559c6)
