[patch 0/2] Speed up build (+drop gdbtui)

[Jan Kratochvil]

Hi,

with 2m55.153s to relink GDB on ARM I rather optimized the build this morning
which has been discussed to be done for years.

benchmark: cd gdb;rm libgdb.a gdb gdbtui;sync;time make

x86_64, ld.bfd (not gold):
FSF GDB HEAD      0m3.427s
1/2=drop gdbtui   0m2.641s
2/2=drop libgdb.a 0m1.877s

arm, ld.bfd (not gold):
FSF GDB HEAD      2m55.153s
1/2=drop gdbtui   1m39.842s
2/2=drop libgdb.a 1m25.762s

The final performance on ARM Beagle is still not good, one should also switch
to gold.


Regards,
Jan
