[lfs-dev] More on static libs

I've been working with static libraries today.

I was able to remove most of them and got through a complete LFS build.  What 
was left was:

bzip2:/usr/lib/libbz2.a
gcc:/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/libgcc.a
gcc:/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/libgcc_eh.a
gcc:/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/libgcov.a
glibc:/usr/lib/libc.a
glibc:/usr/lib/libc_nonshared.a
glibc:/usr/lib/libcrypt.a
glibc:/usr/lib/libdl.a
glibc:/usr/lib/libg.a
glibc:/usr/lib/libieee.a
glibc:/usr/lib/libm.a
glibc:/usr/lib/libmcheck.a
glibc:/usr/lib/libpthread.a
glibc:/usr/lib/libpthread_nonshared.a
glibc:/usr/lib/librpcsvc.a

However, some additional tests failed.  The *new* failures are:

078-binutils-2.25:FAIL: static preinit array
078-binutils-2.25:FAIL: static init array
078-binutils-2.25:FAIL: static fini array

110-automake-1.15:FAIL: t/lex-clean-cxx.sh
110-automake-1.15:FAIL: t/lex-depend-cxx.sh

I'm having second thoughts about removing the static libraries.  There are 
really not that many in LFS and some in glibc appear to really be needed.  I'm 
not sure if the gcc libraries above are needed or not.

OTOH, Ubuntu 14.04.2 has none of the above libraries in a standard install.

Is removing static libaries really worthwhile?  I'm leaning to no.  It takes 
away options from the user that would be hard to replace without rebuilding the 
entire system.
