The __cond_wait_until_impl function takes a steady_clock timeout, but
then sometimes tries to compare it to a time from the system_clock,

The test requires an FPU, so use -march=armv7-a+fp -mfpu=auto instead
of -march=armv7-a.
We also remove dg-require-effective-target arm_fp_ok, but keep
dg-add-options arm_fp: this enables the test to pass on arm-eabi
configured with default cpu/fpu/mode.

Prior to this, a BSS declaration such as:
int foo;
static int bar;
Generates:
.global foo
.local foo
.comm foo,4,4
.local bar
.comm bar,4,4
Creating symbols:
b foo
0004 b bar
Both symbols are local. However, libbpf bpf_object__variable_offs
Libbpf does not treat paddings after functions well. If function
symbols does not cover a whole text section, it will emit error
similar to:

Each instruction in BPF is a multiple of 8 bytes, so align the
functions to 8 bytes, simil
