[Bug ada/45298] New: GNATMake fails with multiple, equal -mcpu options

[michael dot gurlitz at gmail dot com]

Passing a -mcpu=xxx option after a regular argument (a filename), when an
equivalent -mcpu=xxx option was specified earlier, causes gnatmake to fail:

$ gnatmake -mcpu=7400 hello -o hello.exe -bargs -mcpu=7400 rtems_init.o
Exception name: SYSTEM.ASSERTIONS.ASSERT_FAILURE
Message: make.adb:7473

gnatmake: INTERNAL ERROR. Please report.

$ powerpc-rtems4.11-gnatmake -mcpu=7400 hello -o hello.exe -bargs -mcpu=7400
rtems_init.o
Exception name: SYSTEM.ASSERTIONS.ASSERT_FAILURE
Message: make.adb:7473

gnatmake: INTERNAL ERROR. Please report.

Removing either -mcpu=7400 option allows for compilation, and the resulting
executable works. I found this bug when compiling an RTEMS sample program which
for some reason specified many arguments twice (-bargs, -D__ppc_generic, etc.).
However, I believe that issue was related to my environment at the time, since
I haven't been able to recreate it.
