Request: Add Support for Altering ABI Target When Building for riscv64 Platform

[CamberLoid]

In build/ck.build.riscv64:

ck/build/ck.build.riscv64

Line 1 in 6e8e5be

CFLAGS+=-mabi=lp64

Default profile when building ck on riscv64 platform will set the ABI to lp64. However, the actual ABI for different riscv64 ports of distributions may vary (in my case it is lp64d). This issue may break the building process.

I think it would be better if we can allow altering the ABI target when running configure.

@CamberLoid Would it be possible to get a patch?

Would love to include a change for this. Please note configure allows you to just specify a build profile where you can save all these settings. This isn't on my personal priority list so I won't be putting in additional time for the change, but I would gladly test and accept a patch.
