0Day robots reported there is compiling issue for 'csky' ARCH
when CONFIG_DEBUG_FORCE_DATA_SECTION_ALIGNED is enabled [1]:
"
All errors (new ones prefixed by >>):
{standard input}: Assembler messages:
>> {standard input}:2277: Error: pcrel offset for branch to .LS000B too far (0x3c)
"
Which has been discussed in [2]. And as there is no solution for csky
yet, add some dependency for this config to limit it to several ARCHs
which have no compiling issue so far.

There are cases that a commit from one domain changes the function
address alignment of other domains, and cause magic performance
