What is a good way of detecting the bare-metal targets? *-elf*, *-eabi*?

Well spotted. The nit is real enough. What happens is this (with
unpatched mainline):
Checking multilib configuration for libgfortran...
mkdir -p -- v850-unknown-elf/libgfortran
Configuring in v850-unknown-elf/libgfortran
configure: creating cache ./config.cache
[...]
checking for access... yes
checking for fork... yes
checking for execl... no
[...]
The same tests with fr30-unknown-elf:
checking for access... no
checking for fork... no
checking for execl... no
Other examples: gettimeofday, link, mkstemp, pipe, stat, time and wait.
