Thanks.  For me, with this patch applied on top of current git master,
build-many-glibcs $workdir compilers hppa-linux-gnu succeeds, and
build-many-glibcs $workdir glibcs hppa-linux-gnu shows only these test
failures:


FAIL: elf/check-execstack
FAIL: elf/check-textrel
Summary of test results:
      2 FAIL
   1149 PASS
     31 XFAIL

I also manually checked: check-local-headers.out is an empty file;
nptl/tst-cond24 and nptl/tst-cond25 were successfully created (but I can't run
them).  There must be something else going on.

Here is the command line that failed for you:

gcc tst-cond24.c -c -std=gnu11 -fgnu89-inline  -O2 -Wall -Werror -Wundef
-Wwrite-strings -fmerge-all-constants -fno-stack-protector -frounding-math -g
-Wstrict-prototypes -Wold-style-definition           -I../include

And here's the equivalent that succeeds for me:

hppa-glibc-linux-gnu-gcc tst-cond24.c -c -std=gnu11 -fgnu89-inline  -O2 -Wall
-Werror -Wundef -Wwrite-strings -fmerge-all-constants -fno-stack-protector

I have a bad feeling that this is a cross-compilation/native-compilation
issue...
