Since commit fd8171fe52b5e("target/hexagon: import lexer for idef-parser") the hexagon target uses 'flex' to generate idef-parser. However 'focal' may not have 'flex' pre-installed, consequently following error is seen with travis when trying to execute the 'GCC (user)' job that also tries to build hexagon user binary:
<snip> export CONFIG="--disable-containers --disable-system" <snip> Program flex found: NO ../target/hexagon/meson.build:179:4: ERROR: Program 'flex' not found or not executable <snip> Fix this by explicitly add 'flex' to the list of addon apt-packages for the 'GCC (user)' job.
