support: Suppress clang warning on tst-timespec
clang warns that converting from TIME_T_MAX to double (upper_bound)
loses precision (from 9223372036854775807 to 9223372036854775808):
tst-timespec.c:290:19: error: implicit conversion from 'time_t' (aka
'long') to 'double' changes value from 9223372036854775807 to
9223372036854775808 [-Werror,-Wimplicit-const-int-float-conversion]
.upper_bound = TIME_T_MAX, .lower_bound = 1, .result = 1,
^~~~~~~~~~
tst-timespec.c:48:20: note: expanded from macro 'TIME_T_MAX'
#define TIME_T_MAX TYPE_MAXIMUM (time_t)
^~~~~~~~~~~~~~~~~~~~~
../include/intprops.h:57:4: note: expanded from macro 'TYPE_MAXIMUM'
((t) (! TYPE_SIGNED (t)

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It does not matter for the test.
Checked on x86_64-linux-gnu.
