I have just experienced the problem. It looks like this is a relative 
path issue actually:
When you look at mpfr.mk the patch command is the following:
( cd $(MPFR_DIR); patch -p1 -N -Z < $(MPFR_PATCH_SOURCE); )
with MPFR_PATCH_SOURCE:=$(DL_DIR)/$(MPFR_PATCH_FILE) which is replaced 
in my case by ./dl/mpfr-2.4.1.patch where it should be an absolute path.
