Bug#747881: r-base: Error in linker flag causes rpy2 to FTBFS on GNU/Hurd

Hi,

rpy2 FTBFS on GNU/Hurd, when compiling the build stops at

"/usr/lib/R/bin/R" CMD config --ldflags
Invalid substring
-export-dynamic
in string
-export-dynamic -fopenmp  -L/usr/lib/R/lib -lR -lpcre -llzma -lbz2 -lz -lrt -ldl -lm

This is caused by an error in a linker flag in the generated file
/etc/R/Makeconf of package r-base. The attached patch fixes this
problem by using the correct linker directive for variable main_ldflags
in configure.ac

Thanks!
