This commit sets `CONFIG_NEWLIB_LIBC_MIN_REQUIRED_HEAP_SIZE=2048` for the
SiFive HiFive1 board. Otherwise, the test fails on the following assert
from Newlib:
memory space available for newlib heap is less than the minimum required
size specified by CONFIG_NEWLIB_LIBC_MIN_REQUIRED_HEAP_SIZE

add boards/nucleo_c031c6.conf with
CONFIG_NEWLIB_LIBC_MIN_REQUIRED_HEAP_SIZE=4096
to avoid twister issue due to a too low heap size on the co31c6
