bug#45165: binutils-mesboot0 fails at configure, cannot find lex

[Carl Dong]

Hi Janneke!

Oh, that’s a very good find! I have no idea why config.cache is not writable… 
This is most strange!

I checked that my mountpoints have enough free space… Not sure what else to 
check?

Looking at `guix describe`, I’m on bf8dfe3df025e4ac80cccb87497b4f072ba10e2a 

Cheers,
Carl Dong
