make check failures on armv7l

[Paul Zimmermann]

       Hi,

with glibc master f17164b I get some failures from make check, among which:

FAIL: elf/tst-glibc-hwcaps-prepend-cache
FAIL: stdio-common/tst-vfprintf-width-prec-mem

Glibc was configured with ../configure --prefix=/usr CC="gcc -march=native",
configure says armv7l-unknown-linux-gnueabihf, and gcc is version 8.3.0.

Is that expected?
Paul
