./mach build error and other requests

[kesazmarango]

Dear gnuzilla devs,

I installed the IceCat repository and ran the makeicecat script in the gnuzilla directory. I then changed directories to gnuzilla/output/icecat-78.14.0 and entered the ./mach build command. I then got this error:

"""

Config object not found by mach.
 0:00.25 Clobber not needed.
 0:00.25 Adding make options from None
    MOZ_OBJDIR=/home/user/Desktop/gnuzilla/output/icecat-78.14.0/obj-x86_64-pc-linux-gnu
    OBJDIR=/home/user/Desktop/gnuzilla/output/icecat-78.14.0/obj-x86_64-pc-linux-gnu
Error running mach:

    ['build']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

Exception: Could not find a suitable make implementation.

please update the README documentation, I believe it is outdated.

Thank you for your work
