This is to fix gprbuild 24 on Mac OS. The error is > ld: library not found for -lcrt0.o The gprbuild call `gcc -static ...` during linking a main, but MacOS X was never able to do [static linking][1]. The gprbuild reads `-static` option from `*.bexch` file. The `*.bexch` file is created by `gprbind` by reading `b__<main>.adb` generated by `gnatbind`. The `gnatbind` writes `-static` to `b__<main>.adb` for ages, but gprbuild 22 filtered this option. The filtering was removed in [the commit][2].

gnat-aarch64-darwin-13.2.0-x.tar.gzfor MacOS X ARM.I've dropped
gprbuildpart, because I can't build it. Version 24.0 fails (even on x86_64) because the script callsgcc -staticwhile linking gprbuild executable and MacOS X doesn't support static linking. To be investigated.Cross should work for arm and riscv when gprbuild is ready. But avrlib fails fails with
machineaarch64-apple' not recognized. However cross archives have name collision: both x86_64 and arm64 have namegnat-riscv64-elf-darwin-13.2.0-1.tar.gz`SPARK depends on gnatcoll/gprbuild also.
