Description of problem:

vifm assumes that MAX_ARG_STRLEN macro is safe to use if it is defined. But it's definition uses PAGE_SIZE which is not defined on AArch64 (as it can be 4K or 64K there).

Version-Release number of selected component (if applicable):

0.8-1

How reproducible:

always

Steps to Reproduce:
1. build on aarch64 (with arm-koji)

Actual results:
