Since -1 isn't a power of two, compiler may reject it, hide memalign from
Clang 19 which issues an error:
tst-memalign.c:86:31: error: requested alignment is not a power of 2 [-Werror,-Wnon-power-of-two-alignment]
86 | p = memalign (-1, pagesize);
| ^~
tst-memalign.c:86:31: error: requested alignment must be 4294967296 bytes or smaller; maximum alignment assumed [-Werror,-Wbuiltin-assume-aligned-alignment]
86 | p = memalign (-1, pagesize);
| ^~
Update tst-malloc-aux.h to hide all malloc functions and include it in
all malloc tests to prevent compiler from optimizing out any malloc
functions.
Tested with Clang 19.1.5 and GCC 15 20241206 for BZ #32366.
