libphobos: Define main function as extern(C) when compiling without D runtime (PR102476)
The default supplied main function as read when compiling with `-fmain'
has extern(D) linkage. However this does not work when mixing this
option together with `-fno-druntime'.
PR d/102476
gcc/testsuite/ChangeLog:
* gdc.dg/pr102476.d: New test.
libphobos/ChangeLog:
* libdruntime/__main.di: Define main function as extern(C) when
compiling without D runtime.
