[Bug bootstrap/15039] New: using --enable-checking=valgrind with non-standard installation

[Tobias dot Schlueter at physik dot uni-muenchen dot de]

there is no documentation on how to use --enable-checking=valgrind, when
valgrind is installed, but can't be found during configuration. Something like
--with-valgrind=... or --valgrind-includes=... doesn't work. Setting
C_INCLUDE_PATH to the appropriate directory works, but IMHO there should be an
option to configure.

My configure-command is:
tobi@marktplatz build-valgrind]$ ../gcc/configure --prefix=/home/tobi/usr
--enable-languages=c,f95 --with-gmp=/home/tobi/usr --enable-checking=valgrind
when building it fails (not surprisingly) with:
...
checking for unistd.h... yes
checking valgrind.h usability... no
checking valgrind.h presence... no
checking for valgrind.h... no
checking for VALGRIND_DISCARD in <valgrind/memcheck.h>... no
checking for VALGRIND_DISCARD in <memcheck.h>... no
checking for valgrind... /home/tobi/usr/bin/valgrind
configure: error: *** Can't find both valgrind and valgrind/memcheck.h,
memcheck.h or valgrind.h
make: *** [configure-gcc] Error 1
