running remap_land with --print_memory flag fails on Mac OS

[ilaflott]

Describe the bug
Attempting to run remap_land with --print_memory flag results in the following error message on Mac OS:

Error from pe 0: tool_util.c: Can not open ascii file /proc/self/status

The directory structure pointed to on Mac OS does not exist by default, and creating it involves loosening the read-only permissions of this area in Mac OS- not a desirable approach!

To Reproduce
Compile code in build directory as usual, then run code with and without the --print_memory flag

cd build/t/Test10
../../tools/remap_land/remap_land --file_type land --src_mosaic C48_mosaic/C48_mosaic.nc   --dst_mosaic C192_mosaic/C192_mosaic.nc  --src_restart src_restart/land.res   --dst_restart land.res  --dst_cold_restart dst_cold_restart/land.res   --remap_file remap_file_C48_to_C192 --print_memory
../../tools/remap_land/remap_land --file_type land --src_mosaic C48_mosaic/C48_mosaic.nc   --dst_mosaic C192_mosaic/C192_mosaic.nc  --src_restart src_restart/land.res   --dst_restart land.res  --dst_cold_restart dst_cold_restart/land.res   --remap_file remap_file_C48_to_C192 

The first execution fails, while the second runs to completion successfully.

Expected behavior
Similar to behavior without the print_memory flag, except actually writing the relevant output to a text file in an area with appropriate permissions under MacOS

System Environment
Describe the system environment, include:

• OS: MacOS 12.5 (Intel)
• netCDF Version: 4.9.0
