In my case:
$ rm ./stmp-fixinc ; time make -j16
takes 17 seconds, where I can reduce it easily with the suggested
change. Then I get to 11.2 seconds.
The scripts searches ~2500 folders in my case with total 20K header
files.
fixincludes/ChangeLog:
* fixinc.in: Use mkdir -p rather that a loop.
Some system headers can be broken by the machine_name fix performed
by GCC during the fixincludes step. According to the comment in
fixincludes/fixinc.h:130 :
On some platforms, machine_name doesn't work properly and
breaks some of the header files. Since everything works
properly without it, just wipe the macro list to
disable the fix.
So we can just skip it to avoid trouble.
fixincludes/
* fixinc.in: Skip machine_name fix on powerpc*-*-linux*.
