I have a working PIC project that I built in MPLABX IDE v1.21 on windows. I am trying to setup a linux platform on ubuntu linux (a virtual box at the moment) where I've installed mplab v1.26. I've cloned the project over to the linux machine using a git repo, I'm pretty sure I have all of the relevant files committed. I'm using the makefiles that has been auto-generated by mplab. When I run make on the linux machine, I get the following errors (the same method works like a charm on windows):

make: cmd.exe: Command not found
make -f nbproject/Makefile-XC16_24FJ256GA110.mk SUBPROJECTS= .clean-conf
make: cmd.exe: Command not found
make: *** [.clean-impl] Error 127

I'm pretty sure cmd.exe is a windows binary. I assume I need to tell mplab to produce a makefile for linux somehow, but not sure how.

Yes - 'cmd.exe' is a windows thing. The equivalent would be 'bash' or 'sh' or whatever shell you use.
Even so, my guess would be that whatever 'make' is trying to execute would be wrong as it probably assumes a Windows program and not the Linux equivalent. Also the file paths wil probably be wrong (and nto just the wrong format - some shells will cope with that)
I would recommend that you create a new project in MPLABx, copy the code form the GIT repository into the project folders and hook them up to the IDE. That you will have a better chance that the IDE will be generating the correct 'make' script for the environment.
That is a very old version of MLPABx.

Why are you using ancient versions of MPLAB X?
