microperl-5.12.4 fails with parallel make

Hi,

host-microperl-5.12.4 fails to build when parallel make is used (-j32) on a 16-core processor. BR2_JLEVEL is set to 32. The build log is along these lines:

make[2]: Entering directory /home/testuser/buildroot/output/build/host-microperl-5.12.4/cpan/IPC-SysV' make[2]: Entering directory /home/testuser/buildroot/output/build/host-microperl-5.12.4/ext/Hash-Util-FieldHash' Writing Makefile for I18N::Langinfo

Warning: No Makefile!

It builds fine with -j1.
