Remove all matches containing a string until its next space

I want to delete all matches in a text following this pattern:
  • Each match starts with linux-
  • Each match ends with a space
  • (Remove linux-* until immediate next space)


EXAMPLE:
From this text:
Code:
ibudev1 libudev1 libweather-ion7 libxatracker2 linux-generic linux-headers-generic linux-image-generic linux-libc-dev linux-signed-generic mesa-va-drivers mesa-va-drivers mesa-vdpau-drivers mesa-vdpau-drivers milou

Get this:
Code:
ibudev1 libudev1 libweather-ion7 libxatracker2 mesa-va-drivers mesa-va-drivers mesa-vdpau-drivers mesa-vdpau-drivers milou

It is meant to be run on Ubuntu, so use bash, sed, awk, etc... the linux versions and if possible posix for any system (cygwin, etc) better.
