bug#48611: Allow DEJAGNU TIMEOUT env var for slow arches

[Héctor Orón Martínez]

Hello,

Please consider allowing custom timeout environment variable for slow
architectures, such m68k. The following change we carry in Debian
distribution:

Description: timeout for m68k and maybe arm should be doubled
 The timeout in /usr/share/dejagnu/remote.exp:257 is too short for many
 of gcc's testcases, when run on m68k and arm. Include a hack to define
 a specific timeout via an environment variable.
