 force ld to not cache symbols tables.
 This patch, wich should be considered Debian-only (in other words, it should
 not be pushed upstream), forces ld to not cache the symbol tables of input
 files in memory to avoid memory exhaustion during the linking phase.
 .
 This might make linking slower but reducing the overall memory consumption.

 do not pass -wl,--gc-sections on powerpc, s390, arm*, mips*, ix86 when building
             libQtWebKit.so; works around a binutils bug that results in a
             segfault on powerpc, internal link error on s390 and OOM on armel/mipsel.

 fix (workaround) build on gnu/hurd
 Apparently PTHREAD_MUTEX_NORMAL and PTHREAD_MUTEX_DEFAULT cannot be used
 in preprocessor expressions, so temporarly use directly the code which would
 be used on GNU/Hurd.

have glibc. Not yet upstreamed. Requires a upstreamming of the gnukfreebsd patch
