On Darwin10 it's possible to make a 32b PPC build using the
'Rosetta' emulator. However, these builds need to make use of
Darwin9 crts (for exes, dylibs and bundles). This adds the
change to cater for bundles.
tested on powerpc-darwin10 cross from x86-64-darwin16 and on
x86-64-darwin16.
gcc/ChangeLog:
2019-12-14 Iain Sandoe <i...@sandoe.co.uk>
* config/darwin.h (DARWIN_EXTRA_SPECS): Add new
bundle spec. (DARWIN_BUNDLE1_SPEC): New.
(STARTFILE_SPEC): Use darwin bundle spec.
* config/rs6000/darwin.h (DARWIN_BUNDLE1_SPEC): New.
(DARWIN_DYLIB1_SPEC): Delete duplicate.
