[Minios-devel] [PATCH 2/2] Makefile.uk: workaround the string operation corruption

[Jia He <justin.he@xxxxxxx>]

When start a helloworld app with newlib, there will be a boot crash
on arm64 plat:
[    0.000000] Info: [libkvmplat] setup.clibkvmplat @ 51   : Found device tree

Some fdt nodes are parsed incorrectly, especially for those compatible
strings with "\0“.

To work around the bug in newlib, we'd better enable PREFER_SIZE_OVER_SPEED
before we resolve the bug.
