build fails dumping R code in 'methods' on i686-pc-linux-gnu (PR#1630)

Using the same settings in config.site as were used for R-1.4.1,
R-1.5.0 fails to build.

./configure --enable-R-shlib

Using defaults and using PPro optimizations, the build failed in
package methods:

dumping R code in package 'methods'
gmake[4]: *** [../../../library/methods/R/all.rda] Error 139
gmake[4]: Leaving directory `/mnt/Data/src/install/R-1.5.0/src/library/methods'

The command that fails is:

    ../../../bin/R --vanilla --verbose < all.R

The same failure occurs using defaults for CFLAGS, etc.

Install patches:

  zcat R-release.diff.gz | patch -p1

R is now configured for i686-pc-linux-gnu
