linuxptp: Use environment compiler settings

If the machine uses hard floating point, the build fails as below:

arm-oel-linux-gnueabi-gcc -Wall ...
In file included from .../build/tmp/sysroots/imx6qsabresd/usr/include/features.h:402:0,
                 from .../build/tmp/sysroots/imx6qsabresd/usr/include/errno.h:28,
                 from clock.c:19:
.../build/tmp/sysroots/imx6qsabresd/usr/include/gnu/stubs.h:7:29:
    fatal error: gnu/stubs-soft.h: No such file or directory
 # include <gnu/stubs-soft.h>

This patch fixes the build system to reuse the CC variable and also
passes over the defined CFLAGS so the choosen optimization and build
options are respected.

irssi: add --with-ncurses option

* otherwise do_configure tries to find ncurses.h on host and
  disables ncurses support when not found, then build fails because
  of missing -lcurses when using terminfo-core.o:
  | terminfo-core.o: In function `_set_bg':
