is there a compelling reason that execv() is used rather than execvp() in 
gdbserver/linux-low.c ?  seems it's just always been that way ...

personally, i find it annoying having to do:
# gdbserver :1234 /bin/ls /
on my embedded board instead of:
# gdbserver :1234 ls /

having used native gdb a lot more, i typo this pretty often since gdb will 
search $PATH for the program to run ;(
