See attached dmraid build-log and buildroot config.
This happens with a clean rebuild (rm *build*; make).

The dmraid-build system seems to ignore the implicit rules in make.tmpl when 
building with -j2:
/home/development/buildroot/build_i586/staging_dir/usr/bin/i586-linux-uclibc-gcc -Os -pipe -Os  -I/home/development/buildroot/build_i586/staging_dir/usr/include -I/home/development/buildroot/build_i586/staging_dir/include --sysroot=/home/development/buildroot/build_i586/staging_dir/ -isysroot /home/development/buildroot/build_i586/staging_dir -mtune=i586 -march=i586 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -DDMRAID_NATIVE_LOG -DHAVE_GETOPTLONG -fPIC -Wall -Wundef -Wcast-align -Wwrite-strings -Winline -DDMRAID_TEST -O2 -D_LARGEFILE64_SOURCE  -L/home/development/buildroot/build_i586/staging_dir/lib -L/home/development/buildroot/build_i586/staging_dir/usr/lib --sysroot=/home/development/buildroot/build_i586/staging_dir/  tools/dmraid.c   -o tools/dmraid

Building with -j1:
/home/development/buildroot/build_i586/staging_dir/usr/bin/i586-linux-uclibc-gcc -Os -pipe -Os  -I/home/development/buildroot/build_i586/staging_dir/usr/include -I/home/development/buildroot/build_i586/staging_dir/include --sysroot=/home/development/buildroot/build_i586/staging_dir/ -isysroot /home/development/buildroot/build_i586/staging_dir -mtune=i586 -march=i586 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -MM -MF dmraid.d -I  -I. -I../include -I../lib -O2 -DDMRAID_NATIVE_LOG -DHAVE_GETOPTLONG -fPIC -Wall -Wundef -Wcast-align -Wwrite-strings -Winline -DDMRAID_TEST -O2 -D_LARGEFILE64_SOURCE dmraid.c; \
        /home/development/buildroot/build_i586/staging_dir/usr/bin/i586-linux-uclibc-gcc -Os -pipe -Os  -I/home/development/buildroot/build_i586/staging_dir/usr/include -I/home/development/buildroot/build_i586/staging_dir/include --sysroot=/home/development/buildroot/build_i586/staging_dir/ -isysroot /home/development/buildroot/build_i586/staging_dir -mtune=i586 -march=i586 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -c -I  -I. -I../include -I../lib -O2 -DDMRAID_NATIVE_LOG -DHAVE_GETOPTLONG -fPIC -Wall -Wundef -Wcast-align -Wwrite-strings -Winline -DDMRAID_TEST -O2 -D_LARGEFILE64_SOURCE dmraid.c -o dmraid.o

$ make --version
GNU Make 3.81

After applying your parallel-build patch it *works*,
so no further actions are needed.
