[Bug libmudflap/42279] New: libmudflap checks with the wrong CPP for execinfo.h

[viriketo at gmail dot com]

Libmudflap receives the host CPP to test the headers with, instead of receiving
the target CPP.
I noticed it having a linux gnu system with glibc and targetting a uclibc
linux.

I will attach a patch with the fix I used.

I already sent the patch to the mailing list mentioned.

I noticed this problem also affects gcc 4.4.2. The same patch can be applied.

Fix for libmudflap + libstdc++v3 for gcc 4.4.2

In gcc 4.4.2, libstdc++v3 is also affected by the CPP probelm.

I attach the fix for gcc 4.4.2 that fixes both libstdc++v3 and libmudflap
builds, and I imagine, any target library build.

Please again send this to the mailing list rather than attaching the fix here.
