[PATCH 07/11] doc: correct grammar in ARM64 cross-compile guide

[Stephen Hemminger <stephen@networkplumber.org>]

Change "files... is" to "files... are" for subject-verb agreement.
Use consistent spelling "toolchain" instead of "tool chain".
Change "distribution" to "distributions" for plural form.
Rephrase "Substitute <target_soc> with" for clarity.
