Fix musl build on Linux
The commit "ada: Add PIE support to backtraces on Linux" uses
_r_debug under Linux unconditionally. It is incorrect since musl
libc does not define _r_debug like glibc.
gcc/ada/
* adaint.c [Linux]: Include <features.h>.
(__gnat_get_executable_load_address) [Linux]: Enable only for
glibc and uClibc.
