freerdp: Add support for uClibc

The stable-1.1 branch of freerdp fails to build when using a uClibc
toolchain because it's using functions which are not implemented in
uClibc, like eventfd_read, eventfd_write and futimes. That is causing
build failures like these ones:

../../libwinpr/synch/libwinpr-synch.so.0.1.0: undefined reference to
`eventfd_read'
../../libwinpr/synch/libwinpr-synch.so.0.1.0: undefined reference to
`eventfd_write'

../../common/libfreerdp-client.so.1.1.0: undefined reference to
`futimes'

Backport upstream patch, with non-applicable parts (new files from
master, but not in the stable-1.1 branch) trimmed down.

Upstream patch:

Subject: [PATCH] Add support for uClibc
The stable-1.1 branch of freerdp fails to build when using a uClibc
toolchain because it's using functions which are not implemented in
uClibc, like eventfd_read, eventfd_write and futimes. That is causing
build failures like these ones:
../../libwinpr/synch/libwinpr-synch.so.0.1.0: undefined reference to

`eventfd_write'
../../common/libfreerdp-client.so.1.1.0: undefined reference to
