As I wrote in the Bugzilla, I'm seeing a related problem.

Namely, I build kernels on one box, with 'make O=<target>', then I mount
<target> on another one over NFS, 'cd' to it and try to install the kernel
modules with 'make modules_install'. This results in 'HOSTCC firmware/ihex2fw'
and 'fatal error: ...: Read-only file system'. It's readily reproducible.

Commenting out line 1130 of Makefile
("$(Q)$(MAKE) -f $(srctree)/scripts/Makefile.fwinst obj=firmware __fw_modinst")
obviously helps, so it looks like Makefile.fwinst needs fixing.

Thanks,
Rafael
